We have a very active ideas portal and when users votes on an idea they become subscribers to that idea. Many of our idea portal users have complained that they receive too many unwanted emails (they are notified any time another portal user makes a comment). The only option these idea portal users have is to unsubscribe from the idea; however, they will not be notified on idea status changing which is what they most care about. Therefore, provide the ability to have a configurable setting related to types of notifications for idea portal subscribers (e.g., only when status changes).
I agree this is needed so we can keep our customers updated on the status of their requests without requiring that they receive emails on all changes.
The main one we'd like to turn off is the email triggered when someone comments.
