History of your nickname.

I used to work at a car repair shop, and somehow, when I started playing Counter-Strike with my friends at clubs, I needed a nickname. One day, I just signed up with this name because it came to mind. And that's how it started... So, the nickname is justified – I really was a "doctor of motors" back then. By the way, it's a unique nickname – if you see it anywhere online, don't doubt it – it's me.
