Stole this one from down in another thread by MasterNoob. I think it is a fabulous idea. Probably 1/8 lobbies I play are flobbies.
Just a quick thought: add "!faill" to report a Lobby as failed, due to a 5-0 roll, or whatever. Let's say we need a majority of votes, so that includes at least one vote of the winning team (in case of a roll)
