I was reading the Dragonlance novels back in the 90s when I first got slow dial-up access. I loved Raistlin, and decided that with a lyne was a more feminine version of the name. I just never really stopped using it. Since it's not prone to much duplication I've never been confused for another poster of the same name, so apparently this is what I'm keeping. I sometimes use my real name too, particularly on writing forums.
