Totally need to hook everyone up with instant messaging on the next game.
Oh no. One time I played the game while signed into chat with a handful of other players. Born from that chat discussion, I learned two or three townie roles, who the bomber was, and somehow, I confused a mafia member into including me in the list of recipients of a message to all other mafia members. This was before the game actually even started. We rebooted the game, everyone got new roles, and then everyone had a lot of fun, but instant messaging can make everything move a whole lot faster than PMs do.
Though, there's no rule against it or anything.
