Ok, these are the people who have joined so far. I'm looking for another 3 people to join to make it a decent game. Sign-ups end tomorrow night whenever I get on.

EDIT: I feel now may be as good a time as any to explain how I will organize the game
What I plan to do is to take a deck of cards and take out whatever many cards as players, plus two. A few (2-4, depending on number of players) will be kings and will represent the Mafioso, other cards will represent various roles as JJF mentioned in the OP. I will draw a card for each player and the card drawn will be their role (mafioso, citizen, cop, etc.). This way, there may be certain roles for any given round. I will announce the number of Mafioso at the beginning of the game. Other than that, day night/voting/pming what you plan to do is the same as before. If I didn't mention something, it probably hasn't/won't change.
