The ICA membership secretary has been in contact with Don, and reports that all is well. The website and email address are unchanged. However, to quote from Don's own reply " a growing number of ISPs don't want to admit that my e-mail server (a private one) is valid. Mails to it are not sent, and mails from me are not accepted."   If contact by email or throught the website fail, then it would seem you have to resort to snail-mail.
