wiki wiki wiki

Every time I have to do some team orientated document creation work I think of some kind of software more comfortable for collaborative work than MS Word. And each time I stumble upon wiki software. Wikipedia is probably the best wiki (and the power of the crowd) example. A good wiki about starting wiki is How_to_start_a_Wiki :). I decided to try a few on my server (php and MySQL as always). Here they are:
MediaWiki
phpWiki
pmWiki.
I’ll let you know about my progress...
