Only set a date if the list will be closed for at least a year. If you intend to use it again during that year do not expire it. Discussion lists When someone sends e-mail to the list, all the subscribers receive a copy. And so, a discussion begins. Each subscriber is sent all postings to the list.
Nothing happens until someone sends e-mail to the list, to start the discussion ball rolling.
Information dissemination lists Only the listowner can send postings to the list. Postings and responses from ordinary subscribers would not be permitted. If subscribers have comments, suggestions or corrections, they can email them to the list owner who can decide whether or not to send a followup to the list based upon the feedback. We use L-Soft International's program called Listserv for Unix which is running on List.uvm.edu managing both types of mailing lists. To begin filling in the form, return to the top.
