Dick, you do not have to prove anything to anyone. The troll is another example of what is wrong with Mudcat.   

If it were ever put to a vote, I would vote to ban "guest" postings - in all threads. Far from turning this site into an exclusive club, it would serve to eliminate crap like that. If someone has something to say to someone, they should not hide behind a mask.

It is an honor and a privalage to be able to share thoughts and conversations with people of your stature. We might not always see eye to eye, but I know I always learn something here.
