Clicking the Select Sites button on the Create User Restriction screen will display the Select Sites for User Restriction screen.

Clicking a site in the lower grid will add the site to the list of restricted sites for that user. The selected sites will display in the top grid. If you would like to remove a site that you previously selected, click the X next to that selection.

Sites can be filtered by choosing the options to the left of the grids.

Once you have selected the appropriate sites for the user, click the Select button in the bottom right corner of the Select Sites for User Restriction screen.

You will be returned to the Create User Restriction screen.
