Higher Logic's moderation feature gives Community and Super Admins the opportunity to review every new Discussion post and Library Entry before they're publicly available. Moderated Libraries will only display new Library Entries when approved by an admin. This feature is often used in open, or Public communities, to ensure content is properly monitored prior to consumption.
NOTE: Only Super Admins can establish moderation for community and stand-alone Libraries. Also, keep in mind that if moderation is desired for a community Library, it's also required for its associated Discussion.
You can establish moderation for any Discussion and its associated Library, and even for individual users, in the Communities > Moderation section of the Admin interface. Refer to the Moderate Users & Content page for more information about establishing moderation, moderating users, setting up moderation notifications, and managing your site-wide Moderation Queue.
