I'm working through, Idunno, and have, since my post above, found some interesting comments from you. Thanks. In this thread, though, you promised thought-provoking input which, so far, seems to have come entirely from the 'dark' side of the fence. Perhaps I read your OP wrongly and you were referring to contributions you could make in other discussions. If so, apologies, chum. Forgive me my trespasses as a raw newcomer finding his way around an amazingly busy board. Bestests. Neil
