ErfurtWiki

"ErfurtWiki is a fast, user-friendly, and highly configurable hypertext management system. It can store its pages and binary content with MySQL, PEARDB/dbx/ADOdb, dba/dbm, PHP-RPC, or flat file databases. It stands out from similar Wiki implementations in that it allows very easy integration into existing Web sites, features case-insensitive WikiLinks, extensive CSS support, multiple admin tools, is not GPLed, and includes documentation. There are over 200 extension plugins, but everything could still be compacted into one core "library" for easier installation and handling. It is useful for larger sites as well as lightweight backend for private homepages, due to its simple image uploading feature."

WikkiTikkiTavi

From the WikkiTikkiTavi Site:

"WikkiTikkiTavi is a wiki engine --- it is a PHP script that runs wiki sites. Wikis are a revolutionary new form of collaboration and online community. Although there exist many WikiEngines and wikis around the world, this wiki is dedicated to the WikkiTikkiTavi and those of you who might want to use it for your wiki.

Why is it called WikkiTikkiTavi? It's a reference to the character Rikki-tikki-tavi, a mongoose whose [story] was told by Rudyard Kipling in the second of his [Jungle Books]. He was a brave mongoose, living the true mongoose spirit, the way WikkiTikkiTavi tries to live the TrueWikiSpirit."
