Your instructor can set up Discussions to help you engage with course content. You can respond to a prompt, view your classmates’ responses, and reply to others’ posts.
Using Discussions
On the Discussions tab, you can view a list of all discussion boards within your course or subscribe to a discussion to receive notifications about it. Pinned boards appear at the top, and the active and closed boards appear underneath. You can manually mark replies as read while reading discussion posts or by changing your discussion settings.
Click on a discussion board name to view the discussion. There are various options for searching, sorting, and adjusting your viewing preferences for threaded replies.
To access group discussions, click the group icon: 
To reply to a post, click Reply under the post. The Rich Content Editor will appear. If you want to reply to a specific user, you can quote another user by clicking the three dots to the right of their post. You can also tag a user by using @ to notify them. When finished, click Reply to post your response. Depending on how your instructor configures the discussion settings, you may be able to edit or delete your reply.
