They can be assigned manually by a user when a family is being entered or even during a change of status. We also have a new family registration form that all parishes can put on their website. (You can find the link to that form under Administrative menu > Church Administration) When a family submits their information via that form they are automatically assigned the status New Register. Notifications are automatically sent to the Parish informing them of new registrations.
The notification received from Gabriel will look as follows:
