because my username is fury. I wouldn't call you aLTRON if you preferred you be called by the exact case of your username. Just the same for me, I prefer the lowercase f and that's all. You may even call me fURY or fUrY or fUry or furY, but never, under any circumstances, capitalize the f.
If you must use a capital f, call me Flurffmeister™ (don't forget the ™ - alt+0153)
