Import Permissions from a Group
You can import permissions from one group to another, which can save you a considerable amount of time. When you set up rights and permissions for one group and import them into the rest of the groups, all groups then have the same rights and permissions. One way you can do this is to set up a group with the fewest rights and permissions granted, then import them to other groups. Then you can modify the groups as necessary with additional rights. In this case, adding permissions to several groups is easier than removing them.
