What are course discussions?
Course discussions are a "forum" style space where your team members can exchange ideas, knowledge, and thoughts with their peers and administrators. In a discussion, you can post a question or topic related to the lesson and start an open discussion amongst your team members.
Users assigned to the course can post their ideas through posts, comment on others' posts, and reply to comments. Administrators can also oversee and moderate the discussion by editing and deleting comments as needed.
