Hi, Charles:
Attached is a screenshot of what my Settings > Forum Admin > Permissions page looks like. I am logged in as an Editing Teacher (default role settings) in a forum and course I created.
Looks like your Moodle admin may have adjusted the default settings for the Editing Teacher role, assuming you have that role in this course (you're not in a Non-Editing Teacher role are you?). Ask your Moodle admin about giving the Editing Teacher role in this course these forum capabilities to archive a forum. It should be a safe thing to do (it's one of the role permission defaults after all). Letting the teachers do the work of changing student forum permissions means the admin doesn't have to do it. Good luck!
