How can I delete a user group?

1. Go to Page Settings from the top dropdown menu
2. Go to the User groups tab
3. Click the Create user group button
4. Here you will find all your user groups, and you can click the Delete button to remove them. Note that when you delete a user group, the users in that group will get the Rights they had as individual users again, so if an Editor user was added to a Viewer-group and you remove this group, the user will get their old Editor rights back.
