Solution
If you would like to change your username but keep your current account then we can help!
You should contact the Member Support department by visitinghttp://support.chess.com/index.php?_m=tickets&_a=submit and include:
1) Your current username
2) Three possible new usernames you would like to have your account changed to (Please list the one you prefer first and the one you least prefer third)
3) The reason you would like to change your account username
Once submitted we will consider your request and send you a response as to whether your account name can be changed.
Please note that you cannot have any spaces or dots in the name, nor any special characters like dots or ^ & * ! " £ $ % ( ) + = ? / \ |It can be either one whole word, or use a dash or underscore as a seperator.
"Edit your profile" doesn't help, "Settings" doesn't help. Thank you!
