To erase a distribution list, select the "Manage Lists" option from Announcer's main page and click the "Next" button.
When the Manage lists page is displayed, select the name of the list from the "Distribution List" text area and click the "Erase List" button. You will be prompted to continue the operation. If you are certain that you want to delete the list, click the "OK" button.
Once a distribution list is erased, it cannot be recovered.
