Well, the simple answer is just this:
1. Go to DreamHost and get a cheap hosting account
2. Install phpBB (that's a very easy one-click install on Dreamhost)
3. Install TWiki 4.02
or even easier (but not as good) MediaWiki which is also a very easy one-click install on Dreamhost
With that, you'll have an easy platform for practically any community. The big issue might much more importantly be getting members (contributors!) and getting content!
