I have a fairly active forum (not running Discourse yet) in which the users heavily depend on email notifications of new activity in their watched threads. However, some threads get really long, really fast, and if it sends a notification for every reply to a user’s post while the user is offline, the user’s inbox will be spammed with far too many notifications. In fact, my forum used to work that way, and many users complained about receiving a notification for every new reply to their posts while they were offline. So I have my current forum configured to only send one notification email per user per thread until the user returns to view the thread. The notification says: “There are one or more updates to this thread:” with a link to the first post the user didn’t read.
Is there any way I can configure this functionality in Discourse? If not, would it be possible to add it?
