Members: Delete All in This View
This feature allows you to delete all the members in the current view. You will be asked to confirm that you want to delete all the members in the current view, including those that could not be displayed due to the number of members. An SQL statement will also display showing you which members will be deleted.
This feature allows you to use the Members: Find Members feature to find a group of members with a certain feature, and then delete them in bulk. For example, you could create a segmentthat selects members whose top level domain is .gov. Then, you could use Members: Find Members to find all members who meet that criterion. Finally, you could use Delete All in This View to delete that group of members.
In order to prevent a list administrator from inadvertently deleting his/her own login rights, ListManager includes a checkbox titled Don't delete list administrators.. This box will be checked by default. If it is checked, then all list administrators will NOT be deleted when the other members are. If the box is unchecked, then all list administrators, including your own login name, will be deleted.
