I was thinking about this, and I really think what this game needs is a wiki! I know we have the game site, but it isn't really user-friendly in terms of layout (a bit tough to navigate) and kind of limited to setting/overarching plot information only, since users can't modify it. Whereas a player-modifiable wiki would be able to hold a much greater deal of information on players, player characters, player-driven plots, and anything else!

I've played in games that used PBWorks (http://pbworks.com/?utm_campaign=wiki-link) as their wiki host, and I have to recommend it - it's very easy to use and understand, and easy to navigate.
