Send comment moderation notifications ONLY to the Author, not to the site Administration address any more.
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 nobody 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, it was made for Multisite :)
You can install it in /plugins/ and activate it site-by-site or network wide. Or you can upload it to /mu-plugins/ for automatic (Must-use) inclusion.
