Well since Charlie has resurrected a dormant thread, I suppose this would present an opportunity to 'splain my username.
You see, I have always been a gearhead, and racing is part of that. I bought a race car in 1989. Fast forward ten years, lots of races and a championship, and somehow a computer inserted itself into the mix. Well I needed an alias for e-mail. I chose Racer X, older brother to Speed Racer. I added my car number, and the rest is history.
From the very first forum I joined it has also been my member name.
