Thanks, Kat

Both are interesting links. The first one is a little long for me to read right now (it's late here) but I shall study it in the morning.

It's funny. When I wrote my original message off-line, I ended it with another plea to not be misunderstood.

When I read it back though before posting, I decide to delete that bit, as I'd thought I might be just repeating myself...
