To remove all members from a Center while in Center mode
Switch to Center mode (for the center in which you want to remove members). The Center Details page displays.
Click the View Members link to display the list of all members for the Center.
Click the small box to the left of the Name heading in the table. This action will check the box beside every name in the list.
Click Remove from center (in the Bulk Actions line above the list). The list will redisplay as empty. Again, note that members are removed from the center but remain active constituents for the overall site.
Note: Members can also be removed from a Center using a Constituent Import operation or a Custom Constituent Import. See Managing Import/Export Operations with MultiCenter Enabled for more information.
