Sorry to be a bother. I did read the sticky about this not being possible, but it looks like that was last edited 3 years ago. Doing a few searches, I have come across numerous posts with this type of request that have been fulfilled (some as recent as a few weeks ago), so I will give it a try.

I would like my user name changed to either one of the following, but preferably the first if it is available:

nak
0xnak

Thank you in advance for your time.
