Excellent idea with charging to change a User Name.
I prefer sticking with my original name. It's easier for peeps to recognize who I am and what's more, I get followed around by Google Bots, Yahoo, MSN and many others because they like me! At least I'd like to think that Hahahahahaha
When you change your User Name, it tells me that you're either hiding something (but that wouldn't work because your IP addy is easy to recognize and you can't change that) or, you saw another cool name during your internet combing and think it to be really cool-beans to have that name. But heck ... I kinda-sorta like getting to know people who they really are and wouldn't want to be surprised to find that YOU have changed your name and I didn't know it.
So yeah, that's my opinion and whom ever you are -- you're already wonderful and awesome and you don't need no stinking name change. Use your "dough aka money" for somewhere else that counts.
