If your instructor allows file attachments, you can attach a file to a discussion reply using the attachment icon. Attachments can be added to both graded and non-graded discussions.

Any attachments added as part of discussions are copied to your user files. Attachments for graded discussions are not counted against your user quota and cannot be deleted.

Notes: 

• If the attachment icon does not display, this option is not available in your course.
• If your attachment causes you to exceed your user file quota, the file may fail to attach to an ungraded discussion.
• If you have permission to edit or delete discussion replies, editing a reply also allows you to remove an attachment.

You can subscribe to entire discussion threads in your courses and be notified when new comments are posted to the topic. If you reply to a discussion, you will automatically be subscribed to discussions and will be notified of updates unless you manually unsubscribed to that discussion. Please note that you cannot subscribe to individual threads within a threaded discussion.

You will automatically be subscribed to discussions you create in your student groups. You will also be subscribed to any new discussions you create in your course, if your instructor has set course permissions that allow you to do so.  

Note: You must specify your notification preferences to receive updates for subscribed discussions.

You can find your peers' feedback for peer reviewed assignments in the sidebar of your Canvas course and on the submission details page.

Your instructor can assign you to review another student's discussion post. You can view peer review notifications in Canvas in the Recent Activity Stream, the To Do list, and from the individual discussion page. Once peer reviews are assigned, you can also be notified according to your Canvas notification preferences.
