In my school, all teachers are non-editing teachers on moodle so that they can collaborate more easily with each other. So when the editing teacher of a course posts things on the News Forum, all users on her course (including those many non editing teachers) receive a post.
As a long-term solution, I would like to remove the News Forum from all courses. How to do that for the whole site at once?
I could also do it by going to each course manually but it will take a long time...
