Paul actually gives his membership number of the NCCA so i would have checked direct with the NCCA on the phone if i was that way inclined :

This is bloody silly, the guy obviosly wants to to it right, he's got some training, some dont bother !
he's asking questions for advice and he gets scrutinised and receives sarcastic comments, as they say if you cant say something positive, say nothing

I admire the guys who still type pages of info to new starters in order to help them. they make the forum what it is.
but telling someone they "should know" stuff will only hurt the industry when some guy in frightened to ask through fear of ridicule and screws up a job because of it.
