A single entry in a comment thread: either the initial comment, pinned to a point, an object or an area of a design document (or to a BOM line), or a reply to it. A comment can mention people or groups using @, and it can be assigned to a Workspace member as a task, either when it is posted or later by converting it. Only the author can edit or delete a comment, and deleting the initial comment also deletes its replies.
