Seems like we agree Wiki is the way to go. So what do we need in the meantime to put something up and get things rolling

Do we want to self host temporarily? if so we'd need

Hosting?

database?

Wiki software? I'm sure we can get something free for a community resource

What else?

I could donate space and bandwidth from my personal hosting, plus a 10gig sql server 2008 db. But we wouldn't have ALTER permission on the DB.

We could also as was mentioned go the google docs route but that seems somewhat cumbersome and migrating to a wiki could be difficult later on.
