Can I change my screen name?

I would like to change my screen name. Should I register like a new user or could you just replace it?

You go in and edited it

Or send me a private message and I’ll change it - let me know what you want as the new one (and give me two in case the first one is not available)

I still have to learn how to send a PM or how to edit names. Thanks a lot.
