What's your nickname, and how did you get it?
When I was very little my parents bought me an early 1970's edition of the first 14 Oz books, by L. Frank Baum. I read them in order, over and over and over again, and fell in love with the Land of Oz and its odd characters; my first fiction writing was a Mary Sue about me going to the Land of Oz.
When my youngest daughter was old enough, I read all those same books to her, and she became so enamored that I searched out some of the other Baum books and other Oz books written after he died. We collected other Oz memorabilia, and I even wrote her very own Mary Sue story, sending her to Oz. When I got online and began searching for an original e-mail address, she suggested Ozma, and there you go.
Unfortunately, Ozma is a girl -- a princess, the ruler of Oz after the Wizard is deposed. That's caused no end of confusion for people who think I'm female!
