Last night, I was in a game with Gyver, Fred, AppleyNo, and some others. They were doing the name-change thing mid-game, as well as some other funny stuff.
So during the night, I had a dream where I found some special secret commands to change my name in a mafia game, and when I did it, AppleyNo was apparently remote connected to some sort of anti-cheating alarm system attached to all SC2 mafia games, and he punished me for game abuse.
I can't join games with you guys anymore. I have weird dreams afterwards.
