According to the Forum Welcome, you can’t change your forum username.

Usernames cannot be changed either. If you want to use a different username, then create the new username and stop using the old one.

Accounts are not deleted, not even for obvious spammers, due to technical limitations of the system. If you don’t want to use the forums anymore, log off and don’t return. We’ll miss you!

There is no way to change your uctsz3tqx2g5 username. The only thing that you can do is change your nickname.
