Ok I checked for you .. this is what you need to do first
Go onto Homepage/Account/Edit profile
Its this page http://www.chess.com/home/edit_profile.html
5th box down
It says get @chess.com email address. Now what you do, is decide what you want yours to be. As long as no-one else on the site has it, it'll be accepted immediately and you can then start using it.
So for example, if you chose 123@chess.com chances are high that someone else already has this one, as we have over 2 million member, but if you chose something thats unique @chess.com
the chances are very low that anyone else could have that.
It doesn't have to include your real name or your Chess.com username, it could be anything you want.
i just created my mail @chess.com
how to check it
