Actually, the multiverse attempts usually goes down when the GM(s) went missing for some reason or another.

Let's see:
-Rilla's attempt(s), he got lazy and stopped trying, Omniverse goes down...twice.
-Tanta's attempt, despite the weird restriction, it goes on for awhile....until Tanta goes missing.
-Crapton's attempt, got some traffic and some regulars, died down when crapton's going missing with only one fight going on.
