On the User Groups tab, you can add the user to one or more user groups. The left-hand list contains all user groups the user could be part of whereas the right-hand list contains all groups the user already belongs to.

1. In the Users tab, double-click the user you want to assign to one or more groups or click the icon.
2. Click the User Groups tab and select in the left-hand list the groups you want the user to be part of. Use Shift or CTRL to select multiple groups.
3. Drag the selection to the right-hand list or use the icon.
4. To remove the user from user groups, select in the right-hand list one or more user groups you no longer want the user to be part of. Drag the selection to the left-hand list or use the icon.

Tip: Use the search box to quickly find user groups in both the left-hand and the right-hand list.
