You create a room and play. You sometimes get a player that does not want to leave your room even when asked to do so. You should have the power to kick him out when the current game is completed. This gives you more power in terms of who you play with. This shouldn't be hard to do and will enhance the experience. I don't want to create a new room every time a player forces me to leave mine because of whatever reason.

it is a good idea but this has been dicussed many times and it hasnt been implented yet so i wouldnt hold your breath.

You can set what rank you want them to be? Why don't you just do that?

Although in theory this is a decent idea, I personally dont like the ability to kick a player out of a room. Its function could be abused.
