I used to be an admin on a bulletin board for hobbyists in Ft. Lauderdale (before the days of the Internet) that was Roman-themed. All of the admins had names of Roman government officials. I chose Questor (should be Quæstor but that æ was not possible), because 1) it was also the name of a character from an Atari video game and 2) it has the feel of being on a quest or hunt. I've been KCQuestor since 1995
Obvious "play-on-words" with the movie theme, based on the state I reside in... and what I like to hear from the ladies at the end of my journey... Whether I'm any good at getting to hear those sounds, I'll leave for others to judge...
When I first started this online thing in the early 90's I was a fan of wrestling and the Undertaker was my favorite character. It seemed a bit too long as a handle so I got rid of the vowels.
