I created several assignments, but then set the availability date for later in the month. All of my students received 30 e-mails and were a little anxious because they all of a sudden had 30 assignments. I don't think these assignments should show up if they are not available yet. Not only does this send many irrelevant e-mails, it clutters their assignments page and their to-do list. We need a way to show only upcoming assignments when the module is published.
For some reason, even though the assignments are not published, my students are still seeing them on their calendar and to-do list.
