This section will show all the usergroups which were created from any registration questions which you set-up to automatically add users to a relevant usergroup as they answered the questions, depending on their response.

To set-up these usergroups go to Admin>Setup>Questionnaire.

When you create a new question in this area, make sure you tick the 'Create User Group' checkbox on the Action dropdown and enter the name of the usergroup you want creating in the Usergroup name field on your answers.
