Hmm, first I should apologise for posting the (response to the followup to the unsubscribe request) to the list... I really had not intended to.
Secondly: some mailing lists have added headers or footers attached to each message giving directions on how to unsubscribe (or otherwise manage one's list entry). It doesn't totally eliminate unsubscribe messages sent to the list, of course, but it does seem to help. Could something like that be implemented for toasters? It only needs 2 or 3 lines giving a URL and/or an e-mail address.
