A Lobby At Last...Or Is It?

With considerable reservations, I finally claim to have a working lobby.  It's taken 14 hours of nearly continuous effort, it's not user friendly, it's not intuitive, it's not informative, and it doesn't work at all the way I want it to, but it allows logins and can enumerate the connected players.

The next two challenges are these:

1. First, how in the world can I test this?  The game runs fine on my own laptop, but on both my work laptop and my wife's, it crashes immediately upon launch.
2. Second, I have to determine the logic for when the game should actually begin.  Right now, my code looks for two connected players who have both signaled ready.  This logic may work, but until I solve Problem #1 above, I won't know for sure.
