In a discussion, you have several options to view and sort discussions. Use the search field [1] to search for replies or specific authors. To filter by unread replies, click the Unread button [2]. You can also collapse and expand [3] all discussion replies.
To subscribe to a discussion, click the Subscribe button [4]. Subscribing to a discussion allows you to follow the discussion and receive notifications as set in your notification preferences. You are automatically subscribed to any discussions you reply to. When you create a discussion in a group—or in a course if you have permission—you are also automatically subscribed to the discussion. If you are subscribed, the button will have a green background. To unsubscribe, click the Subscribe button and the background will turn gray.
To open options for the discussion, click the Options button [5]. Options allows you to mark all existing posts (replies) as read. If your discussion is graded, you can view the rubric for the discussion, if any.
You can view how many unread and replies are in a thread [6]. The number on the left indicates unread replies, while the number on the right indicates the total number of replies.
