Chess.com claims there are more chess.com users than particles in the observable universe (or something like that) so probably all of the 17,000 (3 digit letter combinations) are taken.

But who knows. Maybe there are a few unregistered 3 letter accounts still lurking out there.

What happens if we find them?
