Readers continue to complain to me that they have been dropped from the newsletter mailing. As I have said on a number of occasions, the likely cause is that you forward the newsletter with the URL of the latest posting. This may annoy some recipients who see the unsubscribe option at the bottom of the newsletter and click it, thinking they are unsubscribing from you but in fact disconnecting you from the newsletter.
If you find yourself unsubscribed, just go to the home page and sign up again.
Before forwarding the newsletter, erase the unsubscribe option.
