I try to support this S.U.P.E.R. list by sending messages that are

Succinct and to the point
Useful to many recipients
Positive toward others
Entertaining to the imagination
Relevant to vanagons.

Other messages I send to p-mail or the bit bucket.
Hopefully this message is perceived as S.U.P.E.R.

Cheers, Tom Neal, human being first, vanagon owner later
