Anmarvelous,
The option to select "white/black" has been removed and is now based on your previous game and your opponent's previous game. If you play the same opponent a second time, the side will switch unless the previous game was aborted.

Since the server was restarted. The drop down menu that used to be available in the challenge issuing window is not there any more. Every time I issue a challenge I find myself with the white pieces, why can't I choose black any more like before??
