We have several lists like this. For example, there is a list that includes all faculty members. The list is seldom used, but when it is used, the list owner wants to be certain that the message will be delivered to all faculty members. Since we cannot prevent subscribers from leaving the list or setting their subscriptions to NOMAIL, we have set up a weekly job to delete all subscribers and add all current faculty. The issue of whether there might be circumstances in which a subscriber could be prohibited from leaving a list has been debated in this forum in the past. In one of those discussions, it was opined that, if a list is being used by an employer to communicate with employees, the employer may be justified in adopting a policy that prohibits employees from leaving the list. I tend to agree with that position. pdr On Tue, 10 Feb 1998, Angus <[log in to unmask]> wrote: ... >I don't know what kind of list this is.. but I can't think of a list >where people shouldn't have easy leave of any list. ...
