due to some system issues we can't currently process vanity user name changes.
The only exceptions are
- when your user name contains profanity or otherwise breaks the forum rules; which it really shouldn't but if you happen to notice just now and want to come forward, please contact me via PM.
- When your user name includes personal data you don't want to have exposed.
We are working on a fix and a permanent solution and will let you know when it becomes available.
Sorry for any inconvenience this might cause;
