Lists provide a forum for the exchange of information on a particular subject. This document describes the features of lists, the owners' responsibilities, and the major functions of managing a list. Mailing List Features Mailing lists can have different features. When you apply for a mailing list you must specify the type of list you would like. One feature is open vs. closed subscription.
Open subscription allows any user to subscribe to the list without approval from the owner.
Closed subscription requires approval from the list owner. The other feature is open posting vs. moderated posting. Open posting allows all messages sent to the list to be distributed to all members of the list. If your list is intended for free discussion, we recommend open subscription and open posting. The owner is the contact person for FAS Computer Services.
