||Which Open Source Wiki Works For You?|
|Subject:||not a P wiki|
Nice article, even if not so rich of details.
Anyway, give that you checked all P languages let me plug Instiki, a wiki written in ruby wich I really like.
It's installation is super simple, download and run instiki.rb (it come with it's own webserver and storage engine), features multiple markup systems (textile and markdown are the most known), *wikinames* and pages can be expressed in unicode, it has a good revision system, RSS feeds, authentication, and the ability to export sections of the wiki in LaTeX or pdf. Give it a try.
