If you are a system administrator or the list owner, you can access the subscribers list page following the Subscribers link on the Mailing List Settings page.
The Subscribers page contains the list of all E-mail addresses subscribed to the mailing list. For each address additional information (such as the subscriber's real name, number of bounces from this address, etc.) is listed. Each address can be marked, and you can use the Mark All button to mark all list subscribers. You can use the Filter field to display the subscribers with matching addresses only.
Unsubscribe: Mark some subscribers and click this button to unsubscribe them from the list. Depending on the current FeedBack setting value, the LIST module will either unsubscribe them immediately or just send them confirmation requests. If the FeedBack setting (see below) value is Send Welcome, the Good Bye messages are sent to unsubscribed addresses.
Mark failed: Mark some subscribers and click this button to tell the LIST module that mail to those addresses bounced. This can be useful in situations when the LIST module fails to process bounce reports automatically, because they come in a non-standard format. Clicking the Mark Failed button will result in the same actions (increased bounce counter, suspension, and warning generation) as caused by receiving a non-fatal bounce from the marked address.
Set Postings: These controls allow you to change the moderation mode for the selected users. You can select some subscribers and set their posting mode to moderated, prohibited, unmoderated, or special. See the Posting Messages section for more details.
Set Mode: These controls allow you to change the subscription mode for the selected users. See the Subscription Processing section for more details. If the FeedBack setting (see below) value is set to ask Confirmation, the subscription mode is not changed, but a confirmation request for the mode change operation is sent to the marked subscribers.
