The discussions tab in courses allows for faculty and students to interact with one another through discussion forums. Topics within these forums use rich text, allow for attachments and can also be turned into gradable assignments.

Viewing and Replying to Discussions
Whenever you click on a discussion, the body of that discussion will appear towards the lower right hand of the page (1), while the responses to the discussion will appear threaded above it (2). Clicking on any of the responses (3) will open up that particular thread and allow you to submit a reply (4) to it that will be threaded underneath it as well. If for any reason you would prefer a flat view for the discussions, this can be achieved by selecting the "Flat" button towards the top of the topic page.
