I dont know if is possible a room owner to designate mods, but would be big help to care rooms, letting the owner less busy, if were necessary to be absent.
Mods to kick, ban, silence possible troublemakers.
so how give mod status to someone?
While there's indeed the occasional troublemaker, I don't think Rolz has that big enough community that frequents the Tavern that would justify having mods.
Maybe one or two people who Udo would trust in, but nothing more than that.
Sorry for the late reply. I think per-room mods are a good idea, I'd make it so the room owner can designate them. I'm adding this to my to-do list.
