I've seen that mini-wiki's will be part of each game to keep track of canon. That's awesome, I was going to suggest something like that, too, as we are using Google docs for this purpose is several games I'm in.

The other thing we are doing is using Google communities to facilitate better communication. Of course, it would be better if we could do all that here, so I propose a mini-forum for each game be created, where we could create new threads etc. Maybe make optionally visible to the community or to invited guests, but limit posting to members of that game.
