Since it's only the admins who can set up communities perhaps it would be a good idea to create a spot where we all can suggest and discuss what communties we are missing. For what it is worth it's kind of good that a themed/focused instance restrict community creation.
With that out of the way there are two communities I miss here and haven't found on the fediverse.
AskGameMasters - a place for gathering questions about GMing. And encourage them.
LookingForGroup - a place to post game adverts and perhaps also for players to post their desires.
Actually, we're only set for admin-created communities for a short amount of time; After a few days, i plan to turn that off and let anyone create communities, like on reddit. The reason for the restriction is to prevent someone from rushing here and "squatting" on a community that might want to move here from reddit, to get a hold of it before the mods there do.
