In this panel, you can allow users to subscribe to new content notifications.

There are basically four (4) types of notifications:

• Notifications for each new post in a collection (users subscribe to a collection)
• Notifications for each new comment in a collection (users subscribe to a collection)
• Notifications for modified posts and user has permission to moderate it
• Notifications for each new comment on a specific post (users subscribe to a post)

In each case, you can allow users to opt-in but you can also consider members to be automatically subscribed (in which case they can still opt-out). (New in 6.9.2)
