Lobby
From MPP Wiki
A lobby is a channel that does not have a crown or changeable room settings. On MPP and MPPClone, lobbies can be created by creating a new room with the name "lobby" followed by (but not requiring) any number. By normal means, any room cannot become a lobby, but, theoretically, if the channel settings were to change and the setting "lobby" has the value true, the room will become a lobby.
On MPP and MPPClone, the lobby has always had a participant limit of 20 users.
