No mate, I played CS for like 10 years, first 6 years hardcore but I hated CS:S so didnt play that, I didnt see it as CS, coz the sound engine was crap and it didnt feel the same and I could own servers in CS but on source I couldnt so never touched it.
Your prob thinking of someone else, I think there was a world wide clan named SK that was best in the world at one point.
But my name in all games has always been SkScotchegg since I first got a PC like over 10 years ago probably now.
