If I wanted to go about doing this, should I ask an Admin to change my Username, or just go about making a new account? Reason being is that I've grown out of this name about four-ish years ago, and seeing as how it was still on this website when I returned, I just figured I should keep with it.

Is there a way I can change my username?

if you would like your name changed, just ask Kaz.

(NOTE: when it's changed, your login name changes to that too.)
