Across all my courses the Discussion and Announcement sections are blank. The only way I can go to one is if I go back through my email and find one I can click a link to a specific threaded response. I can go to that response, but not to the thread or the section. I have no button at the top of any of my courses in the Discussion section or Announcement section. I can add an Announcement from the Home page. But it does not show up in the Announcement section.
