What is a Mailing List?
• A list moderator moderates a mailing list to ensure that the list always receives and sends appropriate and relevant information to its members.
• When an individual does not moderate the list and postings are sent to list members automatically, the list is an unmoderated list.
• A closed list is one in which membership is not automatic.
• A list administrator oversees one or more mailing lists and can either reject or accept a request to become a list member.
