Here are a couple of sites to get started:

• http://www.wikimatrix.org/
  • Did a search, found that the best wikis for the lab are
    • PmWiki?
    • DokuWiki?
    • MoniWiki?
    • TWiki
• For those interested in creating their own wiki, there are many publicly available "wiki farms", some of which can also make private, password-protected wikis. JotSpot?, OddWiki?, PeanutButterWiki?, SeedWiki?, Socialtext, Wetpaint, Wiki.com, Wikia, and Wikispaces are popular examples of such services; more at List of wiki farms.

Wiki software

• http://twiki.org/ - the Twiki homepage
  • has Tags!
  • lots of cool plugins
  • can group things like pmwiki
• http://www.oddmuse.org/cgi-bin/wiki - the oddmuse webpage.
  • doesn't have the stuff that I need. I want to be able to look at old versions of pages. The recent changes page of this wiki won't let you look up prevous versions.
• DokuWiki? - http://www.splitbrain.org/projects/dokuwiki
• MoniWiki? - http://moniwiki.sourceforge.net/wiki.php
• PmWiki?

In the end, the 3 wikis with all the features I needed:

• MoniWiki?
  • advantages
    • has a neat blog interface, in theory
    • has subpages
  • disadvantages
    • only documented in korean
    • has big security issues
    • acls work in theory, but I couldn't figure them out
• PmWiki?
  • advanatages
    • has everything I needed, and a good wiki in theory
  • disadvantages
    • seems a bit simplistic, didn't have anything I wanted
    • I don't like th e cookbook approach to plugins
    • The wiki syntax is incompatibile with my current wiki
• Twiki
  • advnatages
    • the most features, really easy to maintain
  • disadvantages
    • the wiki syntax sucks.
      • I found a way to fix this though! There is an EditSyntaxPlugin? that does the trick quite nicely
