How do I like a reply in a course announcement as an observer?
You may be able to like replies posted to course announcements. Instructors can choose to allow all course participants to like replies, they can restrict liking to users with grading permissions, or they can turn off the feature for an announcement.
In Course Navigation, click the Announcements link.
Like Announcement Reply
Locate the reply and click the Like icon.
View Liked Reply
The Like icon displays highlighted, indicating you have liked the reply.
When a reply is liked, the Like icon also displays the total number of likes for all users.
View Liking Restriction
If your instructor has restricted the liking option to only users with grading permissions, you cannot like your favorite replies. However, you can still view the total number of likes given to each reply.
