I wondered the same thing at first. But since your current screen name is Callistago, not anxi(sorry I forgot the whole thing) I didn't bother.
It's generally accepted (and possibly a rule) that you must keep to one name, unless you announce otherwise. We have problems with people pretending to be more than one person. I know you didn't mean to do that, but it still helps if you keep to one name.
Thanks!
(I've been away for a few days so if you already made the name change announcement, then please ignore.) :-)
