Always a good idea GUEST,J S Bach.
I posted for a while as "GUEST,Jim", till I realised that there were other "GUEST,Jim"s posting and, not wanting to either take credit or blame for the other GUEST,Jim's posts, I decided to join.
Just posting as GUEST, can't help but get confusing, since anyone who doesn't pick a consistent name, at least for a given thread, will become confused with others who do the same.
