Q: How is spamming and spammers handled on this wiki?
A: As of early 2005, no changes to this wiki, either by editing or adding new pages, are picked up by search engines until 10 hours have passed. All spam on this site is usually deleted in minutes, an hour at the most, making it pointless to try to add spam of any type to this wiki.
Q: Why is there no profanity on Wiki Wiki?
A: Because profanity is below us. Generally it gets removed within a day or so by regular readers - see Delete Insults.
Q: How do I use this WikiGettingStartedFAQ?
A: Well, first read the questions and answers!
Q: So what is this Wiki thing?
A: A collection of Web pages which can be edited by anyone, at any time, from anywhere. (Legend has it that the name Wiki was inspired by the name of the shuttle bus at the Honolulu Airport. "Wiki" is a Hawaiian word for "quick".)
Q: Let me get this straight: Absolutely anyone can just come along and put whatever they like on any page?
A: Yes they can! It's essential to know how this wiki runs. However, we prefer that people exercise some self-restraint and put comments & edits only on the pages where they belong. If you're just in the mood to test out the Wiki software, you are encouraged to play in the Wiki Wiki Sandbox; keep your Text Formatting Rules handy. If you just want to dive into contributing to the discussion on the rest of this wiki, well you're welcome to do that, too.
Of course, if people deviate too much from expected behavior (for example if they post spam, offend people, delete good content, etc.) their posting will get undone. Users of a wiki will defend their work.
Q: But what is a Wiki good for?
A1: Most webpages are less than perfect. If it is a Wiki-page and you are annoyed by something, you can just hit the edit-button and change it! Over time, the site gets better!
A2: Many people can contribute. This allows documentation about something to be easily created, without much effort on the part of a single person.
A3: If we discuss something in a web forum, we can collect all the important arguments on a wiki-page very easily. On this page, you will probably get an overview about all the arguments much better than by reading a long thread in a forum.
A4: There are probably a hundred more uses. You will probably find more on "Meatball":www.usemod.com 
A5: See also the page Wiki Uses on Community Wiki: communitywiki.org
Q: How does a wiki work?
A: In its simplest form, a wiki is a combination of a CGI script and a bunch of plain text files ("pages"). When you request a wiki page, the script loads the corresponding text file, processes its marked-up text into HTML according to the Text Formatting Rules, turns Wiki Words into links, inserts this into a page template, and sends the result to your browser. Clicking on a Wiki Word sends a request for that page to the script, which does the load/process/send thing again.
When you click a page's edit link, the script sends the raw text file to your browser in an edit form. You can now modify the page. Pressing the save button sends the modified text back to the wiki server, which replaces the existing text file with your changed version.
That's the basics. Not all Wiki Engines work exactly like this, but all allow you to edit pages without leaving your Web browser.
Q: The words of your links are running together. Is this a bug?
A: No, it's a feature. ;-) It's how links are created. A side-effect is Accidental Linking, which is a Good Thing(tm).
Q: How come I get lost in all these links in these pages?
A: Well, in a Wiki you should usually think more about which links you want to follow, because there are many more than in usual web pages. Click on links only if you really want to read more about the thing you are clicking on. Often you should not go down too deep into the links at first, but try to get the big picture at first.
Q: How can you make a link that will be opened in a new window?
A: In most browsers, right-click the link and then use the appropriate option from the resulting menu.
Q: What is the best place - for a newbie - to start using/exploring Wiki Wiki?
A: See Welcome Visitors, New User Pages or Starting Points.
Q: Is there an organized Wiki user manual explaining all the editing and create/read/update/delete functions in one place? A million little links is time consuming to navigate.
A: There's no formal manual, but try Starting Points, Welcome Visitors, and Brief Tutorial. And remember, this is a wiki - if you don't find what you want, you can create it or refactor existing pages.
Q: Which page is the Wiki's home page?
A: There isn't one. Wiki's pages aren't hierarchical. That said, some pages are better starting places for people new to the Wiki Wiki Web - New User Pages and Starting Points, for example. There is a Front Page, but it's no more special than any other page.
Q: Doesn't allowing multiple people to edit the same page at the same time often cause one person's changes to cancel out the changes someone else may have just made? For instance, if two people save edits to a page at about the same time, which ever one saves last would overwrite the changes that the person who saved first had just made.
A: Some wikis, including this one, detect and prevent that occurring. See Edit Conflict Resolution.
Q: Is it okay to add text to a page, in order to learn how to do it and nothing more?
A: That's what the Wiki Wiki Sandbox is for. Try it!
Q: When I press the EditText link, why can't I just edit the text on screen directly? Why does Wiki use a form for editing text instead?
A: Wysi Wyg editing doesn't work in every browser. Using a form to edit text does.
Q: How can I reduce the risk of losing my contribution?
A1: Don't overload a Wiki Page with contributions. Insert a link to your contribution on a separate page. Select and copy the text before saving so it's stashed on your clipboard. Or, even better, write small and concise contributions so that you are encouraged to rewrite them more concisely when you lose them.
A2: The short answer is that you can't. The long answer is that Wiki Wiki is a community, and we like to keep our community clean. Some Wiki Zens, affectionately known as Recent Changes Junkies, are constantly monitoring Recent Changes to see the latest contributions. When they see pages that are off-topic, or just tests, they delete them to keep Wiki clean. If you want to test out Wiki Wiki, go to the Wiki Wiki Sandbox. If you want to write something that's more likely to stick around, put it in your Wiki Home Page. Have you ever created one?
A3: Write pages that everyone values.
A4: Not even Ward Cunningham can prevent his edits from being deleted. This is part of Why Wiki Works.
Q: Is there any way to limit access to pages so only a certain "group" can edit specified pages?
A: There is on some wikis, but not on this one.
Q: What are the advantages of Wiki over newsgroups, specially when used among a small number of people? How is Wiki different from a newsgroup?
A1: The big difference is that newsgroups only allow you to append. Wikis allow you to edit anything, even previous posts. Newsgroups are strictly Thread Mode; wikis allow you to use Document Mode.
A2: Wikis produce book-like documents, while newsgroups produce letter-like communications. Wikis are deeper, more towards knowledge.
Q: How do I start a new Wiki page?
A: Edit an existing page (like the Wiki Wiki Sandbox) and include two or more words capitalized and run together (e.g. "WikiWikiSandbox"). Save the page and view it. You'll find the words followed by a question mark. That's a link. Follow that link, add some text, and save the new page.
See Adding New Pages and When To Create Pages.
Q: I'm interested in wikis, and think one might be useful to my group. I want to use Wiki Wiki Web to test how it works, but don't want my test pages deleted. What can I do?
A1: You can set up a test wiki at one of the public Wiki Farms.
A2: The Wiki Wiki Web community is generally tolerant of test pages if they explain their purpose, and give a "delete after" date. (Something like "I created this test page for my ____ group to see if a wiki would be useful. We'll delete it after month day.") Creating Off Topic pages without explanation may be considered Wiki Squatting, which is considered impolite.
Q: How do I make a hyperlink without displaying the URL? So I just want to see (for example) LINK and be able to click on LINK and go to www.something.com .
A: That's called a Free Link, and you can't make them on this Wiki. There used to be a facility for numbering external links (like [1], [2], etc.), but this was disabled for security reasons (see Wiki Wiki Web Faq, Fixing Links for details). If you want to avoid retyping the hyperlink each time you use it, give the link its own page and refer to that page instead. This keeps down the clutter of naked hyperlinks.
Q: How do you add a picture, or sound file to Wiki?
A: You can't store these sorts of files on the Wiki server. But you can find that file somewhere else on the Web, and then include a link to it on a Wiki page.
If you include the URL to an image on a Wiki page, Wiki will recognize it as an image reference and format the HTML accordingly. For example, including the URL
"http://google.com/images/logo.gif" will result in this:
google.com
If you include the URL to a sound file on a Wiki page, Wiki will show it as a link, and readers/listeners will have to click on it to hear it. Like so: www.soundamerica.com . [Hopefully now corrected]
All these files stay over on the other server, so ideally you should find a way to ensure that the file won't be taken down there.
See Text Formatting Rules for more.
Q: How do I add an applet/plugin/etc to a page?
A: You can't. The best you can do is to link to an offsite Web page with the applet, though it won't be inlined like a picture or sound file.
Q: If you want to add a question to a page, should you add it at the bottom or the top?
A1: It's up to you and the page itself. Play nice. Put it where it makes the most sense. Typically at the bottom, or just below that part of the page that inspired your question. Remember to try to keep the page so it reads well, or better yet, reads a bit better than before you contributed.
Q: How do I delete a page?
A: Short answer: edit the page, erasing all the text except the word Deleted But Welcome To Wiki. See How To Delete Pages for more.
Q: How do I rename a page without deleting it and losing its content?
A: Create a page with the new name, copy the old page's content to it, fix the old page's Back Links, then delete the old page.
Q: How can I make it easier for someone to figure out which parts of a page I changed?
A: See Recent Changes Ona Wiki Page.
Q: Maybe I am missing something obvious, but how can you be sure that I don't erase everything?
A: Well, there is always the diff, which you can see if you click on the Edit Copy link at the bottom of any Wiki page. And there is a backup in case of massive vandalism.
See Wiki Erase for more.
Q: How do I report a problem with the operation of Wiki, e.g. editor not loading all of a page?
A: See Too Big To Edit. For other bugs, see Wiki Wiki Bugs.
Q: Is any HTML markup supported? Can you just use HTML and have it rendered?
A1: No. See Text Formatting Rules for details about how to do formatting in Wiki Wiki.
A2: See Why Doesnt Wiki Do Html or usemod.com for the rationale.
Q: I was looking at Wanted Pages. A lot of these seemed to be the names of Java classes, which happen to have the same format as Wiki links. Is there any way to escape something with CapitalizedFirstLettersRunTogether so that it isn't a link?
A: Yes. See Six Single Quotes. Other useful tips are in Text Formatting Rules.
Q: I used accented characters and I got complaints that they weren't showing up. Why is this happening and how can I fix it?
A: They are showing up, except not to everyone. ASCII is the standard of the Internet, not UNICODE, which means accented characters won't display for all users. Indeed, while you could put Japanese on Wiki Wiki without much difficulty, most people just see random garbage.
Q: The previous question about the incapability of showing accented characters stated "ASCII is the standard of the Internet, not UNICODE." This sounds arrogant as ASCII stands for "American Standard Code for Information Interchange." Don't you think it would be better to write with a more positive tone toward UNICODE to broaden the wiki community? Is there a UNICODE-based Wiki Clone?
A: I don't know of any, but I'm writing one right now: Senniki Wiki.
A2: There is a listing over which clones/engines that handle unicode in the Wiki Choicetree
Q: Are you sure that "ASCII is the standard of the Internet, not UNICODE"?
At one time (HTML 2.0)
"The base character set (the SGML BASESET) for HTML is ISO Latin-1."
Later this changed; HTML 4.01 says
"The ASCII character set is not sufficient for a global information system such as the Web, so HTML uses the much more complete character set called the Universal Character Set (UCS) ... equivalent to Unicode"

Q: Is there some way to remember which pages you read while in Wiki? Or some way to easily send page links to another page for editing? E.g. create bookmarks on your own user page?
A: Just bookmark in your browser (e.g., Ctrl D in Netscape) each page you might wish to revisit. Alternatively, you can just edit your user page and type the links in there. Use a bulleted list to make it look nice.
Q: How can I set up a button in my browser to edit the page you are currently looking at?
A: See Edit Page Bookmarklet.
Q: What did I do to get banned? Can I get unbanned if I promise never to do it again?
(Q back at you: How, if banned, did you add your question?)
A: The best way to get banned is to run a program against Wiki that denies service to other sites. Email Ward Cunningham to get unbanned. Include both your domain name and IP address as the Wiki self-protection logic might record either.
Q: Is this project open source?
A: Yes/no. There are umpteen versions of this particular software. While the exact software running this site is not open, some versions are Open Source (but not Free Software). See Wiki In Hyper Perl for one, or The Wiki Way for another. For Free Software versions, see Wiki Wiki Clone.
Q: There are images at the bottom of some Wiki Page's but not others. (Text Formatting Rules has several.) What do they mean?
A: Each image links to a page on another wiki. Those wikis (called Sister Sites) happen to have a page with the same name as the page you're reading. For example, Both the Wiki Wiki Web and Meatball Wiki have pages named TextFormattingRules. If you're on the Wiki Wiki Web's TextFormattingRules page, clicking on the Meatball Wiki image takes you to the TextFormattingRules page on Meatball.
Q: I'm totally new to Wiki. I can't find the right way to start, though I have been to almost every Wiki page... I have this assignment to create a Wiki page. The 'Startpage' has to contain a few links. One link is to add a new Wiki page where you can fill in information about some project. Then when you create this new Wiki page, a link to it should appear on Startpage. Is this possible?
A: Yes, it is possible. Since you're totally new to Wiki, I suggest going to our New User Pages page and then read the pages that it links to. Specific information on how to start new pages is in Adding New Pages (and also One Minute Wiki). By the way, there are over 20,000 Wiki pages, so you'll probably have to spend a long time reading before you've visited them all!
Q: How do I create an edit textbox?
A: You don't really 'create' the edit textbox. You click on the 'EditText' link at the bottom of a page, and that will bring you to an editing page with an edit textbox on it. But then, you already know that since you added this question to this page. Every page automatically has the 'EditText' link on the bottom. Is that what you meant?
Q: After I ZIP-Dumped my pages, how can I restore them from the dump if it is needed?
A: With another script or by hand. What did you expect? And are you sure what you did was legal?
Q: Can I run a wiki on a private intranet? Where can I find information about setting up such a wiki (written for the average, non-technogeek)?
A1: Yes - see Wiki Engines and Running Your Own Wiki Faq.
A2: Setting up a wiki on a private intranet is not different from setting up a wiki for the internet.
Q: I still have no idea what Wiki is for!
A1: Neither does anyone else. But check out Wiki Mission and Wiki Philosophy Faq for some theories.
A2: There are literally hundreds of applications. Open online communities. Personal information management. Product support. Knowledge backbone of an Open Source development community. Teachers use them for their classes. Meatball Wiki is a good place to look further.
Q: How did Wiki Wiki Web get started?
A: See Wiki History.
Q: I heard there is more than one Wiki Wiki Web.
A: There is only one Wiki Wiki Web: this one. There are hundreds of wikis; one way being developed to start to know about them is Tour Bus Stop. Also check out the developing World Wide Wiki:One Big Wiki at www.worldwidewiki.net .
Q: Why are these things so text-centric? Way to kill a potential audience before it even gets started.
A1: Wiki isn't for everyone. This wiki attracts programmers and tech-types, who are used to reading a lot. It's also a lot easier to create and edit text than images.
A2: It's a Less Is More / Wabi Sabi / Do The Simplest Thing That Could Possibly Work thing.
A3:Images and other multimedia content may not be placed here without consent of the author, so it's largely a copyright problem.
Q: Can Wiki damage your health?
A: Becoming a Recent Changes Junkie can certainly damage your chances of having any free time. (And hurt your wrists if you spend too much time at the keyboard!) Repetitive Strain Injury
Q: Can I edit other kinds of documents online? E.g., Microsoft Word or Microsoft Excel files?
A: Nope, only those that are explicitly designed for online or collaborative editing. Those usually require special software. See Wiki Like Things.
Q: What is the difference between a wiki and a blog?
A: Wikis are open to editing. They were created to encourage visitors to collaborate, to improve anything on the wiki. Blogs only allow visitors to comment.
Also, a blog has one owner, who has special privileges. Everyone's equal on a wiki (generally; some do have administrators).
Q: I have edited a page twice. How do I retrieve the last but one content?
A: In general, you can't. However, if you did not view the latest rendered version, the previous rendered version might be in your browser's cache.
For older versions of the page, see c2.com . If you still don't find what you seek, check Google. It caches copies of pages it encounters when it crawls the Web.
Q: Are there other WikiFAQs?
A: Yes, try the following. Some answers are just copied from here, but there are interesting answers not found here. See freemind.freezope.org .
Q: I've seen that Wiki is done in PHP. There are some other wikis called Wiki Wiki Clones. If I create a new wiki, on cgilua, how can it be considered a wiki clone?
A1: Actually, this wiki's engine uses Perl, not PHP. Other Wiki Engines use a wide variety of different languages. A CGI script would be considered a wiki clone if it provided the basic wiki functions: automatic linking between pages, etc.
A2: The term wiki clone is used less and less. Wiki Engine is used instead.
Q: I browsed a bit through the categories and discovered that the game cq2 didn't have a Wiki page yet. Because cq2 has an active community, I decided to make a cq2 page in the game category. They keep deleting it, saying it's Off Topic. How can a game be off-topic when there's a category for games?
A1: This wiki is about programming. The community puts up with certain off-topic content if enough people find it interesting (e.g, geek stuff like Star Trek), but anything offtopic can be, and often is, deleted. Post about programming and you won't get deleted.
A2: Games are Off Topic, but no rule is absolute. Those pages are there because (a) we don't want to start a delete war by killing them, and (b) they made it past Recent Changes a long time ago when Off Topic posts were less of a problem. However, many would like to get rid of them since they are Off Topic. Just because Off Topic material exists now doesn't mean we want more of it. There's far too many Off Topic posts as is and recently, many have begun to not allow it past Recent Changes because they feel Off Topic posts are polluting Wiki more so than usual.
See Please Please Dont Categorize Every Page On Wiki. Mostly, we don't like categories, even though some exist because of a few peoples efforts to put them everywhere. Wiki Is Nota Dictionary, it's a programming site. Talk about programming games and you'll have many people jumping into the discussion; try to list games dictionary-style just to say they exist and you're likely to get deleted. Some survive from sheer popularity since they fit the geek culture, but most don't. You have to survive Recent Changes on merit alone. If you want a page to live, then make sure it in some way relates to or discusses programming, only then will most people consider it On Topic. There are no hard and fast rule, see Wiki Social Norms and Why Wiki Works to get an understanding of the culture here.
Q2: Would a page with a list of great stuff that was once in a game but not anymore, and that should be put in a game more, be allowed? (That's about programming; why don't they program stuff like that into games? Why do they seem to be interested only in having more pixels and higher resolutions and more graphic stuff instead of improving the basics?) It could be turned into a discussion of what should be in a game and what not. I am not that good in expressing myself in English (need more practice), so here is a part of that list: RTS:
The shooting in Total Annihilation, it is realistic, it is real, not just some smoke here and some unit there that gets damage, every shot is flying across the screen and it can hit an enemy or an ally on its way to the target.
Like the round world in Populous 3 (not sure about the name, haven't been able to play it for a long time), not a square map or a map with boundaries, but a real ball shape, round, which allows you to be attacked from every side, instead of hiding in a corner of the map.
A: That's not so much about programming, as it is about specific features of a narrow class of programs. Before you create the page, ask yourself, "Does this page further Wiki's goal of offering insight into how to improve the activity of programming?"
Q: Where should I test things?
A: In the Wiki Wiki Sandbox. Please don't deface working pages with tests.
Q: What is the history of Wiki?
A: See Wiki History.
Q: How to implement a Wiki? Is there a tutorial for it?
A1: See Running Your Own Wiki Faq.
A2: The Wiki Way contains a baseline Perl wiki, lots of explanations and extensions.
Q: Is there a copy of this FAQ written in simplified Chinese?
A: No.
Q: I don't understand. What if someone wants to be bad and deletes all the text?
A: No problem, we will undelete it. See Why Nobody Deletes Wiki.
Q: Aside from the Wiki Wiki Web, what are some other successful wikis?
A: Wiki Pedia, for one. Meat Ball is another. Susning Nu in Sweden. No Smoke in Korea. Linux Wiki in Germany. Dse Wiki in Austria. And, depending on your definition of "successful", hundreds more Public Wiki Forums.
Q: I want visitors to be able to add text to a page (like comments or such), but not be able to edit everything else (i.e. append only). Can you do that with wiki?
A: Depends on the wiki. You can't do it here on the Wiki Wiki Web, but other Wiki Engines might have that feature (e. g. ZWikiWiki and Pro Wiki). If not, Wiki Engines are generally pretty easy to write and modify - you might be able to add the feature yourself.
Q: If I wanted to use wiki in a Web site but keep the Web site template (tables, images, etc..), could I just copy and paste the HTML code from Dreamweaver or something?
A: Depends on the wiki. Some (e.g., Quicki Wiki) use page templates, others don't.
Q:Are there any wikis that are suitable for use by visually impaired or blind people, using screen magnification or reader software?
A:Since wikis are text-centric by nature, most wikis are already friendlier to magnifiers and screen readers than other web sites are. Wiki Case trips up some speech synthesizers on pronunciation (see also Wiki Words Considered Harmful), so it might be preferable to use a wiki that supports hyphens or underscores e.g. Wiki_Words, or Free Link syntax. Many wikis also support skins, themes, or styles via Cascading Style Sheets (CSS), making it possible to design an ultra-simple theme that works well with accessibility tools.
Q:That's great, thanks, but could anyone let me know which wikis in particular support CSS?
A:Depends on what you mean by support. Most Wiki Engines use HTML/CSS templates to render wiki pages which you can adapt to your purposes.
Q:Did the owners of the c2.com website hire more people to run this Wiki?
A: Not in the usual sense of "hire". This wiki is non-commercial (except that it is an Amazon Associate), not even supported by advertising; Ward (the sole owner, and creator of the concept of wiki, and implementor of the world's first wiki: c2 Wiki) pays for the hardware, software, internet connectivity, etc, out of his own personal pocket, and does software, hardware, and network administration himself. He did recently begin to recruit volunteer "stewards" to give him a hand in unspecified ways relating to fighting off attacks by e.g. spammers, but these "stewards" are not paid staff. And how could they be, when Wiki is non-commercial (and receives no grants) in the first place?
Q:You mean I can edit ANY page? Really?
A:Yes really (However, other members may delete or undo your editing as they see fit (Wiki Spam and Wiki Vandal is not tolerated).
Q: Are there any 'plain text wikis' where there is no coding needed?
A: The Pro Wiki Software has a configuration option for making pages, branches of subpages, or a whole wiki 'plain text'.
Q: Can I attach files in Wiki? If so, how?
A1: Not On This Wiki. If you have someplace else where you can host the file, you can certainly provide a link to it from here, just by putting the link in a page. Just be sure it's relevant to this wiki. Some other wiki implementations do optionally support file uploads, but it's generally not a desirable feature for a publicly accessible wiki, due to security concerns.
A2: Rather than attaching files, in Wiki you can point to them. This is preferable due to Once Only. If the File one would have wanted to attach changes in time, the linking mechanism is a much better solution. One will need to have an internet location, such as one's own web site, or one which allows uploading of files, to make this work. This is not an expensive process, since there are many low-cost sites which one can use. (It ranges from 50 to slightly more than 100 dollars per month for such sites.)
Q: Can I upload an excel file and have others edit it on a wiki?
A: See the previous question.
Q: How can I disable the magic formatting codes temporarily? Sometimes I need to type * or # characters as literals, avoiding having them be interpreted as formatting characters.
A: The "*" character is a formatting character only when it starts a line or is preceded on the line by one or more tabs only. You cannot disable formatting on this wiki, but some other wikis have a means to do so.
Q: What is your reasoning behind implementing Perl/CGI for the Wiki Engine? Wouldn't PHP offer more scalability and be less resource intensive on your servers?
A: This wiki is slightly older than PHP. Would PHP be more scalable and less resource intensive? That, I'm afraid, is an essay question with no simple answer. (But there are a lot of wikis implemented in PHP.)
Q: Help me to create a table in wiki, please!
A: If you're talking about this wiki, be aware that tables are a feature that is Not On This Wiki. You can however use monospaced text to lay out information; see Text Formatting Rules.
Q: How can I make replacements here? I mean (c), (TM) etc?
A: Please be clearer: what have © or ™ go to do with replacements?
A2: Do you mean Html Entity? Not On This Wiki. Use Utf Eight instead.
Q: What is a pictoral representation of the frequency table?
A: ???
Q: What is the difference between Wiki and HTML?
A: No angle brackets. See Text Formatting Rules.
Q: What's the difference between a WIKI and a blog?
A: Blogs are organized temporally while Wikis are organized by content. Blogs are largely addend-only (add content, then add comments, rarely editing either), while all parts of a Wiki are generally readily accessible for editing and refactoring. For the most part, content in Blogs is created by a single individual or small group (one->many), whereas Wikis are fully collaborative (many<->many). If one were to compare them, a Blog is more like a diary or newscast and a Wiki is more like a public bulletin board.
There are, of course, exceptions to every rule when it comes to extensional definitions; one could lock down a Wiki and reduce it to a one->many use a 'Wiki' as a news source, for example, or could avoid editing old Wiki pages and get the 'addend only' property.
See Wiki Design Principles, too.
Q: Which Wiki Wiki Clone is just like this one?
A: None. For reasons only known to Ward, he has not released it to the public.
Q: what all architecture patterns can be listed from wiki ?
A: Look in Category Pattern for a starting point.
