Thanks, Trampy. You are a wellspring of knowledge. I anticipated the answer but did not have enough knowledge to explain it. I get the impression from posts I see here on the board that people may be passing info back and forth in PMs thinking that those are truly private. I doubt that many are using PGP. I hope that people will read your response and keep it in mind when sending PMs.

If the moderators have any info along these lines that they would be comfortable sharing, I would be most appreciative.
