A place like heaven (like shift said) where it could be the moderator and admin service room. This means that mods/admin type ::heaven to get to the room where they wait for players to help.
Players would type ::onlinehelp to get to this place where it would say; "You are currently second in line" or "You are currently First in line" in their own chat box. Once its their turn to be help by the mod or admin who is on duty, they will be automatically teleported to the service room.
This is just an idea for the mod or admin to do while they are on duty.
EDIT: Maybe you could also add ::heavenon and ::heavenoff because lets face it, whats the point in players being in line if there is no mod or admin on duty.
