Step 1 of the directions says click the 'View x submitted assignments' link but the actual wording is now "View/grade all submissions' so it needs to be changed.
Grading using the rubric does work, however, step 7 shows as a very, very pale pink instead of red. When JavaScript is disabled step 3 shows green only while the mouse hovers and marks on the criteria then the green turns off as soon as the mouse moves away. With JavaScripts off, step 7 is also very pale pink instead of red.
