Limit commenting capability to subscribers with a new "comment availability" setting. Available in the Comments area of the URL properties, this allows the comment functionality to be a benefit of membership for subscribers. Because most subscription set ups require an address or credit card, users will have more accountability and comments can be more easily tied to real names.
Normally, comments are only available to subscribers on pages where subscription is required. You must log in to view the article and the comments.
However, this new feature allows comments to require subscription even on pages where the article is not behind a paywall. At least one BLOX Subscription service must be defined for the site.
