I guess I'll chime in.. I've had artimis as an internet handle since .. 1993, when i was first introduced to IRC.
Being the wonderful speller I am. I mispelt Artemis. Artemis is the greek Goddess of the moon and of the hunt. (Her roman equivilant is diana - my middle name.), between my major, my fasination with the moon: the handle fit and i've been using it ever since!
