This plugin is designed for administrators to share the task of moderating comments and publishing posts marked as “Pending Review”. It is NOT designed to notify non-admin subscribers of new comments or posts.
The plugin adds checkboxes to the WordPress profile page, allowing you to setup notifications for these events:
<ul>
<li>a comment is added</li>
<li>a comment is held pending approval</li>
<li>a post is pending review, </li>
<li>a post is published</li>
</ul>
If you have permission to edit other users, you can also setup notifications for them… so when you go on holiday, you can set a colleague to receive the comment notifications while you’re away.
Users can only receive notifications for comments if they have the authority to moderate comments, and can only receive post notifications if they have the authority to publish posts.
