Can you adjust discussion permissions at the sub-account level? For example, at theh sub-account level, can you turn on the ability for users to attach files to discussions? This would eliminate the need for faculty to go in and adjust the settings for each course. I've read the "How do I attach a file to a Discussion reply as an instructor?" and the "How do I allow students to attach files to a Discussion?" pages, which make it sound as though the permissions can only be adjusted on the course-level.
