None of my students forum posts are showing up

When I go to mark forum posts it isn't showing any of my students have posted. Thus not allowing me to go in and rate posts Related or Unrelated. I went back and double-checked my dates and they line up with the weekly structure.

Go to your gradebook and go to the Other tab, then click on Weekly Feedback. From there click on the Sync Discussions button on the left hand side. It's right above the listing of the weeks column.
