[Meta] How can I change my username?

Every time I try to visit the forums I receive this error:
“That username is already in use or does not meet the administrator’s standards. If you are Bic and you have forgotten your password, click here.”

My username is "Bic ". As you can see there is a space there, which it allowed me to enter when it prompted me to add a username to my account. I have not been able to find a way to change my username. Is it possible to fix this issue?

Contact Unity Support and they will help you with that: support@unity3d.com

I’ve been contacting unity support for over 2 months and this is still a problem. I had to create a second account just to post this. WTF?
