" I think that registration-required wikis cut against the very idea, and I'd rather have someone who's willing to keep an eye on the timeline instead."
I agree wholeheartedly; on the other hand if this wiki becomes remotely popular, it will be hammered with spam. I've seen the Atom and Codehaus' wikis utterly trashed by spam in the last year; even C2 has had severe problems and that has a large and dedicated community - they believd they could keep it clean faster than the spammers could wreck it, which turned out to be not the case. Please do not underestimate the amount of work a community has to do to keep a wiki straight - it's more like farming than gardening. I'm responsible for the Jython wiki, which runs on MoinMoin. We set that up so that you had to be logged into edit and that has worked well. IME if you let the potential community know what you're doing around editing and why, it's not a problem.
