By adding a user to a user group, you’ll automatically give that individual the same permissions as everyone else in the group—making it easier for you to get them set up with the permissions they’ll need.
Tip: Members of these user groups can also be managed within User Groups.
1. Click Users in the left sidebar.
2. Click the user that needs to be added to a user group.
3. From the General tab > Group Membership section, browse for and select the desired user group.
4. Click [SAVE].
