Goodness me, now we are hearing about a sense of entitlement. Surely if "all who have joined GN have and are entitled to voice & share our opinions & perhaps even learn something new ..." that is an argument against flagging up someone's (whose?) view telling us whether we need no previous knowledge, some knowledge, etc. You seem to have done a "u" turn on this one Bridgeit.
The "only for the brave!" category shouted that this was, as someone called it, a "goady" thread. I haven't seen anything posted, including the usual personal attacks, reference to snobbery, etc., that makes me feel any different.
