The EducationProgram extension currently adds a user preference under the "Misc" tab:
- Show the "Did you know box" on your courses page.
I think this user preference can probably be safely removed. Users who really don't want to see this "did you know" box can presumably hide it via per-user CSS.
A second approach would be to turn this into a hidden user preference (add a small close icon to the "did you know" box that toggles a hidden user preference). We'll just need to figure out how to un-hide the box if a user has hidden it (perhaps via a sidebar link from "Special:MyCourses").
A third approach would be to move this user preference under the "Appearance" user preferences tab.
