What’s the difference between a list administrator and a list moderator?
All lists have a list administrator. Some list also have a list moderator. Both an administrator and a moderator can subscribe and unsubscribe list subscribers, and approve or deny deferred messages. (See “Can I preview messages before they go to my list subscribers?”). The administrator can also modify all list settings available via the list administration web interface. The moderator does not have access to the list administration tools. In general, the list administrator also serves as the list moderator.
