Personal Wiki

What is a PersonalWiki? It's like WardsWiki, but it's yours. It can be:

a free-form database
a PersonalInformationManager
a journal (see WikiJournaling)

Internet wikis that can be used locally (and need a server)

All of them, but the degree of difficulty for installation may vary for each one. (Most PHP installations require an Apache Web server, and some may require mySQL as well.)

ErfurtWiki, 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.)
MediaWiki (The same one that Wikipedia runs on) -- http://www.mediawiki.org/wiki/MediaWiki
MoinMoin (see http://moinmoin.wikiwikiweb.de/MoinMoinAsPim)
PhpWiki (You also need to have EasyPHP or some similar software.)
PmWiki The data is stored in PmWiki-specific file format (you need to have EasyPHP or some similar software).
RuwikiWiki (in Ruby, see http://ruwiki.rubyforge.org/)
SkAverySimpleWiki (Perl on Apache or IIS)
UseModWiki (in Perl)
WackoWiki (apache, mysql)
WiKit (in TCL/TK)
JspWiki (JSP, flat files)
