Unless other people have thoughts on this matter, at first the specs will go something like this:

-sign up for account
-you can start any one game, and join as many open games as you like.
-closing a game doesn't mean you quit it, you can come back and participate, kinda like being in multiple SFMs
-games will go similar to site games, in that they won't be real time.
-add in real time if i ever get a big player base
