Mafia: general discussions.

Well, I would say it again. If you're going to have discussions at night, it's better not to limit them beyond the usual rules. The only caveat: adjust the balance in favor of the Mafia. That's it; you can talk freely. At the same time, there isn't really a pressing need for these discussions: you log in once, when you're sending Night Detective information, see what the smart people are writing, and leave. You don't need to vote anyway, so there's essentially no load time.
That's how I see it.
