We’ve had more complaints from our users on this. As stated before, email notifications for likes are a major driver of traffic back to our site which is still small. Our engagement has dropped (# of posts, visits) since we made the switch from our Ruby on Rails forum, and we think this is the major reason why. I’d love to confirm now that we have a 1 month baseline.
(Note: I’m a bit puzzled by why this isn’t in the control of admins. If our forum takes off and have the problem of too much engagement, it’d be a nice problem to have. We’re paying for added email notifications, so why not let the admins decide if it’s worth it?)
