Aww, c'mon. Kal-L is a Brit while the real Stan Lee is a NYC native. He just doesn't believe you really are Kurt Busiek. Well, that's his business.
No, I don't believe it. The real Kurt Busiek wouldn't waste time taking part in a forum, he's got plenty of other things to do...
In my turn, I might make you believe I am Moebius (aka Giraud) who's drawn Silver Surfer, and put a link to his site.
