You'll need to be an Administrator level user to get this done.
1. Click the ADMIN tab.
2. Click the ACCESS GROUP sub-tab.
3. Click NEW to add a new group, or MODIFY if you wish to modify an existing group.
4. Name the group at the top and check the boxes for each action you wish to RESTRICT (not allow your users to be able to do).
Save and close.
