How are we supposed to communicate ideas with eachother when we can only say our name?
Oh my god. We didn't even think of that. xD
You know though, there's a version of Mafia where each poster is limited to 2 words per post (and one smilie). So they have to play the whole game going:
PersonA: lynch who?
PersonB: BoB, mafia
BoB: Not me
