I'm loving the new reassign tool, and I understand that the due dates don't change, but I have a couple of technical questions. 

• If you graded the assignment, re-assigned it, and a student does not re-submit, does the original grade remain in the gradebook?
• Does it differ at all from allowing multiple attempts (other than placing it back in their dashboard list)?
• Does it also place the assignment back in their To-Do list and calendar?
