Enable Report to Moderator in SharePoint 2013 Community Sites

 In previous version of the discussion boards,  for some high profile enterprise discussion boards required a dedicated resource to monitor for any offensive comments. But in SP 2013 admin can enable reporting of offensive content. As soon as that is enabled users can see a option to Report to Moderator and sends an email to admin's thereafter they can delete such offensive comments. So, users themselves do the moderation instead of a dedicated resource.
