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 visiting http://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 separator.

hi i just wanderd how to enter to chess chat .thanks

Sometime people disables chat, so if your playing against them, you can not post anything.

Are you asking about when you PLAY -> Online Chess or when you PLAY -> Live Chess?

hello , i am also unable to chat in live chess , whenever i try to post by the enter button, the chat box turn into red box.
