According to the baby name book my parents got it out of, it's Greek for "Hunter." According to at least one Greek acquaintance, it's not.
Either way, it's my real name. When I first got online (back in the days of BBSes) the first board I frequented was largely populated by people using their real names. So the idea of a handle never really stuck with me.
Using my real name has served me well over the years, as it's quite unique and folks who've only seen it online tend to recognize it.
