"If you're not part of their very small group, you do not rate a response from them."

You believe the Magic Bullet theory too??? How about Area 51??? Obviously the tin foil in yer hat is wrong side out...

What a load of bollox...

I'd imagine (at least MY case I can speak about with authority) that there's been no response because of my admission that I have little or no tech knowledge, and instead have just made a broad offer to "help where and when I can"

In your case, well, I expect that one must be a MEMBER to help out... A MEMBER who can get and send PMs', a MEMBER who can be reached by email, a MEMBER who isn't a nameless, faceless troll...
