"I had wondered why subwife became Superbitch ( am I the only person who knew that was what happened, everyone else seems surprised...), "

I figured it out on my own pretty much. They posted in the same places, their speech had the same rythym, the post count added up, and I'm 99.99% sure that whomever designed the old subwife avatar also did the fun SuperBitch one as well.

As others have said, whatever the name is, it's the person that matters most and she's a good one.
