This topic describes how course discussions are organized in an edX course.
Discussions are made up of posts, responses, and comments. Together,
posts, responses, and comments are known as contributions, and a post
together with its responses and comments is an exchange.
- Posts initiate a conversation by asking a question or making a statement
for learners to consider.
- Responses reply directly to the post.
- Comments, in turn, reply to specific responses.
The following conversation shows each of these contributions:

18.104.22.168. Right Pane
When you select the Discussion tab, the right pane opens to a home page
that lists ways that you can interact with posts. Each of these interactions is
covered later in this topic. For more information, see the following sections.

message each day that summarizes discussion activity for the posts you are
following. To receive this daily digest, select the Receive updates check
After you select the title of a post, the right pane shows the original post,
responses to the post, and comments on responses. The page is formatted to help
distinguish between posts, responses, and comments:
- The post and its title appear at the top of the page.
- Responses appear indented and with a white background below the original
- Comments on a response appear with a gray background below the response. The
font size for comments is smaller than the font size for responses.
These elements appear in the image below. You can select the image to enlarge
Additionally, in the upper-right corner of every post, response, and comment,
you can see several option icons. The icons that you see depend on the type of
