Click on 'My account' at the right. Click on 'Edit'. Click on 'Additional Information'.

There you will see your user name. Change it. Save.

Almost, William. There, you can ‘only’ change your full name . For a change of the user name, TTFKAY has to contact a moderator. Who’s a moderator? Check the Read Me page.

Ah, at one time you could do it yourself, but I guess that's changed.

Yes, sometime ago there was something to change even the subdomain but now...
which of the moderators should i contact?
