Discussions are online comment threads that facilitate collaboration around particular items. A web site production team, for example, can use discussions to sharing feedback about content before publishing it. Development teams can use discussions to brainstorm, debate, and reach consensus about product design, and specifications.

Most items (such as documents or rich media files) have an attached discussion page. Folder, and note pages have embedded discussions shown below the list of child items in a folder or the body of a note. You can add, edit, delete, and reply to comments in a discussion, but you cannot select or edit a discussion apart from its parent item.

Each new version of an item shares the same discussion as the immediately preceding version. A WDK setting can change this default behavior so that discussions are only shared for each new minor or branch version (while major versions have new discussions), or that no versions of an object share a discussion (every version has its own). In this manner, an object’s versions can provide a sort of timeline for an object, along with the comments in each discussion. When a discussion is shared by versions, version markers for each checkin appear among the comments.
