I picked the handle "Gerbil" back in the days when I was posting messages on various BBS and FIDOnet groups. I wanted something other than what seemed to be the typical choice of tough-sounding nicknames like "Doom Bringer", "World Destroyer", "Flaming Dragon", etc.
So I picked the name of a small furry desert rodent that many people keep as pets in a cage at home.
Little did I know then that I would be forever being asked if I was gay. Took me a while to figure it out...
The Screaming_Gerbil handle is because the image I had in mind was this cute furry little rodent screaming at the top of his little lungs...
Not that he's screaming because he's being inserted into some place dark and foreboding...
