I moved away from Texas and Texas is in my screen name, can I change it?
Nope.
You might reach out to WGT to discuss a new account to replace this one.
DO NOT open a new one on your own - you'd risk both!

Why would anyone move away from Texas???
Well, unless you were in Austin.................. :-)
Seriously, try what alosso said - and do NOT create a second account!
That second account option is definitely viable, WGT laid out a way to do it. In the OP's case, his investment is minimal and he doesn't play a lot so closing his current account and opening another is OK as long as he doesn't compete until he reaches his previous level and lets WGT know. They do the closing.
I guess it boils down to how important the name is. :-|
