Silly question about User Names

[Kakariko Kid]

Is it possible to change your user name? Even I first came to this site, it was to simply add a trivia and get out. So, I used my work email user name since it would be easy to remember if I needed to come back for any reason. Now, I feel pretty regular and my last name with my middle initial kinda stinks in my opinion. I want a unique name like y'all. Like maybe - Mr Bass Boom Stick (yes, that's a play on Shaggy's song).
