That will close his entire account. He might just be talking about premium (paid) membership.

If you want to cancel premium membership you can go to your account page and you will find a notice that will say:

You have a Platinum Membership, scheduled to renew on xxxxxx xx xxxx.
Thank you for supporting Chess.com! To cancel your Premium Membership, click here.

Just follow this link : http://www.chess.com/home/account.html . It's at the top.
