A discussion thread is created as reviewers add comments or suggest changes to a topic. The Discussion pane displays along with the topic in Reviews. You can choose to display the Discussion pane below or to the right of the topic content, or to minimize the Discussion pane.
This feature enables other participants in the review to easily comment on a suggestion or to take other actions, such as agree or disagree. Editors can accept or reject suggestions. The discussions are interactive in much the same way as social media discussions.
The discussion content is visible while the topic is in the review phase. Suggestions can be made, and reviewers and editors have the option to reply, to agree and disagree, and to accept or reject. When the topic moves to the editorial phase, the discussion pane remains visible, but new suggestions can't be added.
