Ah, yes, Monique, I hadn't thought about that "genius" thing, but it rings a bell.
Actually, I thought both came from the Middle Eastern (Arabic?) word "djin" - as in Aladdin's "genie."

I took "Genie" as a user name instead of "Jeannie," which my grandpa always called me, because I thought it was a less common spelling. No pretentions on my part of being either brilliant or magical. LOL
