Roger! Don't go away - I do appreciate your input - given your knowledge, you are definitely an asset to this discussion board.

I do agree that healthy critical discussion is welcome.

We have had a couple of minor posts from persons unknown that were unwanted - but I guess that's what happens out here on the internet.

Hopefully here we won't get all the trash postings that have caused me to quit reading the USENET posts (meaning all the off-subject spamming).
