s3rv0, derived from Tom Servo. See my avatar, here or in game. Several friends and I in high school bought a very expensive, very top of the line server. Not rented it, we bought it, built it, and sent it to a company in Chicago to have it hosted. We ran several counterstrike servers, and when looking for a theme for our community/niche of friends, we chose Mystery Science Theater 3000. Those of us who all knew each other chose our aliases, and as one of the two original founders, I got the coveted Tom Servo. We had a bustling community, and had great fun adminning (and occasionally abusing, to the chagrin of all) our pubbers. Eventually, after becoming broke college students, we couldn't afford to run the servers anymore, so the community ended, but the legacy lives on. I replaced letters with numbers to make the name more original and nerdify it a bit, and took out the Tom to also make it a bit more unique.
And MrCool: Did you really just dig up a thread started almost 3 years ago just to yell "repost" at someone? Come on, be glad someone finally posted a threat that doesn't include a bounty or a lame youtube video.
