Naming policy a joke?

[Caloosadesign]

I am new to the server as of a week ago. I was so excited to start a character once I logged on. During the creation stage I tried about 5 different names that I've used been using the past 15 years. None of them worked. Then I tried the random name function three different times. All were rejected. Then just as a joke I typed in "mcdouble" and it took. Now I'm stuck with a name of a cheeseburger. Is there a way to change names?
