How can I find what a specific user group is used for? I am reviewing our user accounts but found a group that doesn't seem to appear in any job services and I cannot figure out what its value is (nor who the contact may be).
Have you checked the documentation for Groups? https://support.avoka.com/kb/display/Manager/Groups
If the group is an Alert Group, it is used to provide lists of people to be notified of certain events. These wouldn't be in a Job Service.
If the group is a Form Group, it is used to control access to Forms, and the Tasks associated with those Forms/the Group. These also wouldn't necessarily be seen in a Job Service.
You can see the Group's definition under the Security menu → Groups. This will show what kind of Group, who are the members, what permissions the Group has. It does not track a Group Owner or contact.
You might be able to figure out who created the Group by checking the Security menu → Audit Log, and filtering on Group entities. Set the Start Date back a bit to get more data. The audit logs are purged though, so this data may have been cleaned up already.
