With respect, a lad comes onto a photography forum, and says he wants to be a pro photographer, has taken some good shots on his phone, hasn't heard of an slr, and has no idea in which area he would like to work...a little ribbing is to be expected, isn't it? I'm still not convinced this isn't a wind up.
I'm all for encouraging up and comers...but I wouldn't post on a motorbike forum saying I hadn't passed my test yet but how do I go about becoming a pro racer cos I'm really good on playstation, or go on a cooking forum saying I'd seen Gordon Ramsay on the telly and I want to be a pro chef, and I'm really good at microwaving meals...
I don't think the abuse dished out has been in any way harsh, it's just been a little gentle poking, mixed in with a whole heap of sound advice.
Lighten up a little, a bit of humour won't hurt him.
