I understand users and their associated email address relative to managing notifications. What if I want to add a "Notification Contact" and them use that for notifications of someone that does not need a user ID, they just need the notification email's for a failed sensor. If I create a new Notification Contact, I can't figure out how to use that notification contact in notification template or even add the contact to a group to more easily manage notifications. I must be missing something in my understanding. Please help enlighten me.
