To activate or suspend a user:
Use the left mouse button to select each user name you want to activate or suspend.
Left-clicking on a user name and pressing the Shift key as you move your cursor selects a consecutive set of user names. Press the Ctrl key and left-click individual user names to select multiple non-consecutive user names.
Click the
button to move users from the Active column to the Suspended
column, thus suspending them, or click the button to move users from the
Suspended column to the Active column,
thus activating them.
