Groups can be assigned to user profiles and can be used for segmentation purposes. A user profile can have multiple Groups assigned to it. Administrators are able to create Groups, which form part of a catalogue that is available for all sites to use.
We have a selection of example Groups, such as Fire Warden or HR Contact, that can be applied to your site, or you can choose to create your own Groups in the Taxonomy section of the Site Settings.
Please note, Groups are referred to as Roles in Site Settings.
