A Wiki Home Page is just a Wiki Page where the title is your name. You can make a Wiki Home Page by smashing your first and last names together like this: Ward Cunningham. You can then use that as your Wiki Signature.
See Adding New Pages if you don't know how to add a new page to Wiki.
It is conventional to put 'Category Home Page' into each Wiki Home Page. (If you're new to Wiki, and don't understand what a category or a Wiki Tag is, don't fret; you'll pick it up as you go along. Besides, a Wiki Gnome will probably add Category Home Page to your Wiki Home Page for you.)
A Home Page that is not accessed for a long time could be marked for deletion, example below:
AreYouThere? OrphanPage, February 1, 2004; last edited March 14, 2002.
Do backlinks get checked before actual delete?
If the Wiki Gnome is doing the job right, yes.
A home page on Wards Wiki is a great way to get your page (and not the pages
ten-million-odd other slobs with the same name as you) high on Google's hit list. Especially if you edit lots of other pages on Wiki and thus have lots of BackLink''''''s. (There's another one.) -- ScottJohnson ''GoogleLovesWiki.''
Actually, most of the time, when you edit these wikis, no-one re-edits them... so it gets quite a bit too boring at times.
That's true - but this wiki is different.
So the content on the wiki page is not guaranteed ... it's like an announcement on a board that everyone edits to his liking so the initial idea is rarely conveyed? -- user exploring the wiki concept
