Change Username?

[Imco]

I couldn't find this anywhere, so I thought I'd just ask.

This might be a very very very dumb and impolite question, but I'm asking it anyways
Is there anyway to change my username from Imcotjuh to Imco97?
Imcotjuh is a username I used to use when I was a bit younger, "tjuh" makes Imco a diminutive, and I'm not that small anymore
Is there anyone I need to contact for this issue?
Can I do it myself?
Is it even possible?

You need to send a PM to an admin.
