Sometime in the last four months, there was a post to a page describing
various wikis and comparing them to MediaWiki. I've spent about a half
hour looking through the mailing list archives unsuccessfully (gads, my
poor eyeballs!). There was information in that particular article that I
wanted. I think the article was found on a MediaWiki-hosted site. The
author was working on some kind of wiki himself. Ring any bells?
