Interesting thread, for which thanks, Guest. But it would be helpful if you put something in the "from" line when you post, or you just show up as "guest" - which is fine in a trouble-free thread like this one (or it is until another guest or two weigh in, then it is impossible to know which guest is saying what). Of course you could even become a member - no charge, no obligation, no spam, just some useful benefits.
