The effect of that would be to wall off certain areas of the forum for discussions among "initiates only" which would not, IMHO, be a good thing.

Also, having no direct experience of something doesn't seem to stop most of us from chatting about it. The whole point is surely to discover new things, often by asking really dumb and ignorant questions. That's my approach anyway.

OTOH, I do understand where you are coming from. Perhaps, with Michael's approval, we can try to use this thread to arrive at some constructive understanding and/or ground rules?
