Rob Church exclaimed:
If MediaWiki doesn't do what you want, *and there is something which does, or is more likely to*, then pick the right software for the job!
And for those wondering what that might be, you might want to glance over TikiWiki:
It's a wiki *plus* workflow *plus* trackers *plus* maps *plus* surveys *plus* quizzes *plus* calendar *plus* forums *plus* image galleries *plus* blogs *plus* newsletters *plus* .... etc. etc. etc.
I personally use MediaWiki because a plain (but world-class) wiki engine is *almost* what I want, and I'm prepared to do the work to make it go the extra few yards. For people who want a wiki plus tons of other stuff, all pre-packaged and ready to go, TikiWiki looks like a worthy candidate. MediaWiki's extensibility is great, but if you're trying to develop a site where the wiki is only a small part of the eventual software, then it's probably the wrong way to go.
(I'm sure there are others, too, but TikiWiki is one I happened to come across. I haven't tried it, use at your own risk, yadda yadda yadda.)
