Since they're allowing you into the lobby before you're finished connecting, I highly suggest that it displays 'connecting' or some sort of business until you are connected to someone.
In addition, considering how bogged down it can get if multiple people are connecting to multiple other people, I suggest a Queue where people join one at a time...just based off what I'm seeing this minute....that is, one person connects to everyone else in lobby, then the next person does the same.
Oh, and an odd Test name thing is showing up
Also if the host changes slots available it seems as though people are still connecting despite no available slots.
