Well vic, this is a continuing problem on every forum that I visit and moderate at. You are member # 1483, and there must be hundreds of people that sign on during the day and
just lurk. I have trouble NOT writing and find it an easier to learn by asking questions, commenting on what others say, etc.
So, to answer your question, I have no idea why they don't post? Afraid of ridicule, afraid they'll look or sound stupid? Expect others to answer questions they already know? {{I look up things up in my books, as I sure as hell don't have it memorized}} or they are lazy and figure others will answer the questions and provide them entertainment.
I know, I sound negative recently...
