Think wikis are cool and want to set one up on your own web page?

Here's some research we've done while looking into such a project ourselves. 
(1) A good review article of different wiki softwares / engines with nice descriptions of some of their benefits and drawbacks
(2) Installation instructions for Media Wiki, which is free one that Wikipedia uses and is recommended by guy above and listed in this review chart comparing various wiki engines
(3) Download page for mediawiki from sourceforge
(4) Another good, free wiki engine, jsp , has blog integration, also mentioned in same comparison chart above, jsp described here
(5) This review wiki of top 10 wikis is good
(6) Top 10 review site says MoinMoin is great, easy to use, etc.
