Then maybe if its full, instead of just trying over and over, it asks the host if its ok and displays whos trying to join, you could have the options: No, Yes, Ignore and Enter Now, where no would return a message to the joiner telling them the host refuses them to auto retry, yes would just let them auto retry, Enter Now would then ask you to click someones name, it would kick them and let the person trying to join in, and ignore would tell the joiner no and disable future auto retry requests until that person is taken of the ignore list.
