To create a new user group select “Manage > Users and groups” from the top menu. Then click the “NEW GROUP” button in the groups panel.
The group will be created a child of whichever group is selected when you click the “NEW GROUP” button. New groups cannot have the same name as other groups with the same parent group.
NB Grouping flows hierarchically, ie to be in a child group you must be in a parent group. When users are added to a child group they automatically become a member of the parent group(s) above it. Find out more about group hierarchies.
