Game room bell

[uncle]

There should be a tool which would inform the owner of a currently full room about other players in the lobby who want to join the game.

The "bell" could be allowed to use only once (to prevent abuse); when it is clicked, in the game room is a bell sound played and something like this would appear somewhere on the screen:

Players who want to join: Uncle, xxx, yyy

While I'm not exactly sure about the concrete implementation (you may need to expire such requests, for example), I generally like this idea.
