Relax mw, we're all guilty of promulgating the dreaded thread drift. You're posts are well thought out and unlike some here (who shall remain nameless) that seem in need of misinterpreting plain English to advance their agenda of the moment, you think and write clearly with comprehensible logic.
I've been emailing with a fellow who was entertaining and informative in his posting. He backed away from the forum because he was tired of some members going out of their way to argue and was "invited" to stop posting by one member. Jesus wept.
