\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
for all viewers on the resource. Course members will see new discussion
on their Navigation screens. Instructors may allow course members
to post anonymously or not, and course personnel can see who posted
the anonymous messages. Anonymous only prevents students from seeing
the poster. (Sometime instructors or TAs post anonymously to discreetly
help the students.) Course personnel may hide or delete inappropriate
messages.

Users use the same mechanisms to post to resources and to send internal
email to resource authors or course administrators, and the user can
do more than one of these things at the same time with a message simply
by clicking multiple checkboxes.
