I can't even imagine playing so many games simultaneously.
However, I also fail to understand why some of you can get upset because someone else chooses to do so! Calm down folks. It doesn't do you any harm.
Personally, i would have thought it would be more satisfying to play bullet chess. At least that way you opponent is moving quickly as well. Playing thousands of correspondence games against people who are going to spend at least a minute or two on their move means you must just spend all your time losing. Where's the fun in that?
