This thread may be better suited for the Off-Topic subforum, but how big is this other chess site? If they're small, you have a better chance of snagging something special. This is coming from someone who has a 3 letter chess-related username on ICC. If it's
Chess.com, so much is already taken that you'd probably have to sit there typing names in until you found one that wasn't taken. If it's some small forum, you could just try common chess terms and one might work.
