Actually I'm an Aussie but I was born in Germany. Whether or not it's derogatory depends on the person I suppose. Personally I don't really care, at work I get called Kraut, Jerry, Bosch, Nazi and the very first nickname I got when I was an apprentice was LJB which stands for little jew burner (not very nice or politically correct) but you don't get to choose your nicknames. I can tell if people are saying stuff in fun or if they mean to piss me off and I react accordingly. So in short call me what ever you want but don't call me late for dinner I'm working on my CAD model for my guitar at the moment, I'll post a jpeg of it when I'm done. Hopefully I'll get some ideas
