All the blogs have a Meta (Facebook) comments box on them by default.
If you want to moderate those comments here: https://developers.Meta (Facebook).com/tools/comments
First you need to get an APP ID, by adding a new APP https://developers.Meta (Facebook).com/apps
And save your Meta (Facebook) APP ID, and admin username in the global contacts area in the CMS, then publish...
Your Meta (Facebook) admin username, is your personal Meta (Facebook) account username, not your page username, and not your login email.
Create a personal username here: https://www.Meta (Facebook).com/username/
You can then moderate all posts in the one place in Meta (Facebook), and hopefully you get notifications also
