Actually I just went on their discord server and I ended up talking to an organizer, and they added MarioBoards to the list.
Sooooooo they actually might be participating.
@Mellow Ezlo I haven't seen this post on MarioBoards, which has recently revived its Mafia community.
Do you think you could post this on that forum as well? I'm sure someone there (maybe me) will love to represent.
