Reopening Blackboard is a full song and dance. Possibly the biggest pain there's ever been, and it doesn't help that there's always one or two students who are consistently messing up. I believe my policy on it was that it's out of my hands if you turn in the wrong assignment, and if you try to make it up through email, know that you're starting out around the B-range, and it'll only get lower from there unless your paper is golden enough to stick at a B+.
Most knew better, but like I said, it's always those couple students that always manage to mess up otherwise easy instructions. At least put in the effort, and I won't mind keeping you out of the D range, but if you're sending me a sentence because the assignment is late and you gave up, what am I supposed to give you other than the lowest grade possible?
