I have 13 games going at the moment and am trying to join "Dark and Atomic Challenge (Dark Chess)". It is in the single game format and the note says to have at least 5 slots open. I have 7, but it won't let me sign up. "grenv" had a tournament posting a few weeks ago called "Dark Chess Challenge #2", that I had signed up for. As far as I can tell, he cancelled it and then posted the Dark and Atomic tournaments. The only thing I can think of is that cancelling the tournament left my name on the list somehow even though it is no longer visible on the tournament board. Any help or ideas for me? Thank you.
