\label{Resource_Discussion} Unless banned by an instructor, all resources in the course can host discussion, which means students may post comments that will appear to all viewers. Course members will see new discussion on their Navigation screens. Instructors may allow course members to post anonymously or not, and course personnel can still see who posted the anonymous messages. "Anonymous" only prevents students from knowing who posted. (Sometimes instructors or TAs post anonymously to discreetly help the students.) Course personnel may hide or delete inappropriate messages. To participate in a discussion on the a resource, click the \underbar{Post Discussion} link at the bottom of a resource. If you want to reply back to a particular post, then click the appropriate \underbar{Reply} link.
