This idea was recently brought up on the LIAISON list. I think it would be a possible solution to the "blabla no longer works/studies/has an account here" problem. LISTSERV could allow for the list owner to specify a "normal subscription period" if any. It might also be nice for LISTSERV to send out warnings stating that "your subscription will end on ... unless you re-subscribe". Another possible solution might be for LISTSERV to automatically cancel subscriptions if it gets mail "returned to sender, address unknown" ( perhaps on two different days? during one week? ), but this solution seems more prone to problems. Comments anyone? Tony
