Allows the comment moderation notification ONLY to the post author and no longer to the main site admin e-mail address too.
There is no settings page. The plugin will do only one thing : make comment moderation notifications go to the authors e-mail address, and no longer the site moderator address.
To test if it is working:
This plugin does not send any messages. It only changes the addressee of the comment moderation queue notifications that are sent by WordPress.
If you do not get any of these notifications, disable the plugin and test again. You will probably still not get any notifications and the problem lies with WordPress not being able to send emails via PHP. There are other plugins or tutorials about server configuration that can help you with that...
Yep. You can install it in /plugins/ and activate it site-by-site or network wide. Or you can opload it to /mu-plugins/ for automatic (Must-use) inclusion.
