Gosh, I'm kinda with Dark Penguin on this one - with weird names, it's easier to remember who's who and what they're like than when you're trying to keep "John Smith" and "Dave Smith" straight...
But if we're going to change, then I second the motion for people to put their old names in their signature line.
If you really, really, want to change mine, then I'll become Lisa Nikodym. (nniko wasn't very interesting anyway)
Lisa
