My Idea is that since every time A known GM joins a room, It gets silent, or if someone is spamming/breaking rules or such, they stop entirely, So my idea is for a GM to have the choice to join a room "Silently" In which doesn't show their name in the player list or announce that they joined in the chat. This could give them the chance to catch people breaking rules in action. They wont always have to join Silently, They could do something like /sjoin <Room name> Or something similar.
