Email notification for replies
 

Where in the admincp can I modify the option so that users will get a notification by email when their threads are being replied by other users?

Thank you.

This is a per-user setting. They can subscribe to threads in a variety of ways. In their Settings they have an option to subscribe by instant email by default. But they can also do it when they post, or later with a dropdown in the thread.

Note that on shared servers this can cause email overload.
