What is a Personal Wiki? It's like Wards Wiki, but it's yours. It can be:
a free-form database
a journal (see Wiki Journaling)
Internet wikis that need a server, but can be run locally
The degree of difficulty for installation varies -- most PHP installations require an Apache Web server, and some may require mySQL as well. Windows users check out XAMPP for an easy-to-use Apache/PHP/MySQL platform.
Media Wiki (The same one that Wikipedia runs on) -- www.mediawiki.org
Moin Moin (see moinmoin.wikiwikiweb.de )
Doku Wiki uses PHP, but doesn't require any database, stores content as plain .txt files -- dokuwiki.org
Pm Wiki The data is stored in Pm Wiki-specific file format (you need to have EasyPHP or some similar software).
Erfurt Wiki, uses PHP - but you can either use MYSQL or a textfile mode. The textfile mode makes it very easy to edit the pages locally. (You need to have EasyPHP or some similar software.)
