I have tried to contact WGT about changing my name. Didn't think at the time I was giving out too much information. Can anyone help.
Seeing how you want to do things by the book or within WGT guidelines, it would not hurt to ask.
I have heard / read that WGT facilitated some people changing over their accounts in the past, in particular those who were using facebook. So, WGT has clearly helped facilitate some form of account changeover before, but it could mean starting over. I don't know.
The other thread linked by dodgyputter suggests they can do nothing...
That being said, if it is a privacy concern and you have felt harassed or people tracking you down somehow, report that and give it as a basis for your request. If WGT won't protect you from being harassed, then there are other golf games out there - some appear more popular than WGT.
