I've been thinking about changing mine to match up with my practise, and I'm not sure if I can take the plunge. I'm really attached to being known as Catloaf around here.
It's also a very enthusiast-based username that makes me feel all warm and fuzzy inside. I dunno guys, I can't let it go, but I almost wanna!
How about you? What was your old username if you changed it, and why? Do you miss it?
