IRC Mafia is a form of TBT Mafia played in the #belltreemafia channel in the IRC. To play, you'll need to join the IRC. You can do this from any IRC chat client, or from the website itself. Our chat is located at this link. Once you choose your username, you'll be in the main TBT chat, which is #belltree. To join the channel used for Mafia, type in the following: /join #belltreemafia. When you're in the channel, you'll need to have the MafiaTBT user in there. This is the bot that runs the game that Justin sets up when a game will happen.
