bowieboy and JarethsGirl are pretty much on the same crappy par. I did try a different username once. CandidKate. I missed the old one and came crawling back.
If you ARE going to change your username, make sure you are really dedicated to the new name. Otherwise, you'll probably get homesick for the old one like I did.
In the mean time, you should have people come up with suggestions for the new name. I suggest: KillerTravoltaCondomMan... though I'm pretty sure someone's already got it.
