I'm trying to change a discussion board assignment from not-graded to "graded," but the gray box won't allow me to check it. I accidentally double-posted the assignment, and one of them (that most students used to access the discussion) did not have the "graded" box checked. I just finished a chat with support, and she said it shouldn't be a problem to switch it to "graded" even tho students already began submissions. Yet I am unable to do this in the Edit function.
I'm horrified to think I may have to go through all 100+ posts and tease out each student's work....
