Email notifications for moderated topics/replies – solved!

I have previously raised this problem that, when an admin approves a moderated topic, subscribers are not notified.

I have created a solution by developing an extended version of the plugin pending-submission-notifications that does the equivalent thing for moderated posts.

It does this by hooking onto the ‘transition_post_status’ and thus works when a post/topic/reply is published from front or backends.

You can find the code on GitHub here.
