Forum Games Permissions

Is any sort of special permission required to start a long (i.e. 1 week+) forum game or rp? Not just posting games but games with moderately complex rules? I know mafia requires permission (and that's a subject of debate) but what about other games?

If it doesn't already exist, it's a super old topic, and if there are no specific rules of its own (ie elimination or mafia) then you are free to do so

Okay, thanks. Mods, please lock.
