This module adds a new node option Premium content along with core publishing options (Published, Promoted to front page, Sticky at top of lists).
When a node is published as premium content, only users with proper privileges may view the full content of the node.
Non-premium users can still access premium nodes but only get the content rendered in teaser context, even when trying to view the full content. An additional message informs them that the content is available to premium users only.
