Overview

A #Discussion holds a list of comments for a #Node. An inside discussion only appears when the node is not published. A #Comment can be added to an open discussion. Discussions only show in there current language (each traduction gets its own discussion). #Discussions can be created in the ‘drive’ popup or are automatically created when the first comment is added. Discussions are automatically created only if there already exists an outside and open discussion for another language and if the current visitor is a commentator (User.commentator?).
