Groundfine-what would be your criteria for allowing or not someone to post? A PPL-are they qualified to discuss airliner matters? Any CPL (ie, like myself, non-airline) or just airline pilots etc.
Everyone has a right to a point of view and some of the airline crew on this site post incrediably niave or outragious statements and some people who have never flown make some very valid points.
(P.S. I'm not having a go, mate, just stating my opinion, and sorry for going off topic everyone)
