By placing your Facebook Admin ID in the Head of your website, you will recieve notifications everytime a comment is made on your website using the Facebook Comment feature.
This is described in more detail here: https://developers.facebook.com/docs/pl ... structions
To get your FB Admin code, go here and enter your personal profile URL: https://findmyfbid.com/
Once you have your FB Admin code, you will add the following line (replace the xxxxxx with your FB Admin code):
<meta property="fb:admins" content="xxxxxx" />
You can add as many of these lines as you wish to add additional users to be notified.
You can access your header from the main menu by selecting "Settings" -> "Administrator" and then clicking on "Header" in the "Theme editor".
