This plugin enables blog admins and editors to manage the notification of incoming comments. As WordPress only has the option to notify on every comment, the email account of the admin may recieve many email each day. Notification is also limited to the admin only, so only the admin user will receive an email for incoming comments.
Using the plugin you can subscribe to a RSS feed that contains even comments that has to be moderated. Every feed entry has the links to delete a comment, mark a comment as spam or approve a comment, if the comment has to be moderated. If a comment has been marked as spam, it will no longer appear in the feed.
