This has come up a few times since the Mafia discussion on it so I figured I'd be better off just making a post instead of having it keep cropping up.
Out of Game chat is officially allowed. The reason for this is pretty simple:
1. It doesn't affect the Adventure game in nearly the same way as Mafia, in some ways I feel it actually benefits the game.
2. I don't see how I could realistically stop it even if I did want to ban it.
Hosts are allowed to ban it if they want for their games, but if they don't state they are doing so then you have every right to assume it's allowed and won't be penalized for using OOG.
If it is banned for a game and you are caught using OOG you forfeit any points and achievements earned at the end of the game. The host is also allowed to host-kill you if they feel it has harmed their game.
But the important thing to note is it won't be banned very often, if at all, and if it is then it's the host's duty to notify everyone very clearly otherwise it doesn't count :)
