My vote is for voluntary contributions but with two suggestions.
1. We need a mild personal reminder each year. I hope that this could
be automated and sent separately from the Digest itself. And repeated
until we pay up. I am as delinquent as anyone in not paying until I am
2. Now that credit card facilities have been withdrawn it makes sending
$30 from outside the USA very uneconomic.
I am well aware of the costs of charge card facilities. As treasurer
of the British Vintage Wireless Society I have just set up charge card
facilities for the benefit of non-UK members. We were charged GBP200
initial setup fee, plus 5% of transactions or GBP20 per month whichever
is the greater. We are passing on the 5% charge to overseas members.
It is still cheaper for them than a sterling bank draft.
Curiously, it would have cost us more for electronic charge card
facilities than the simple manual ones that we have.
