Continuously refreshes class shopping cart until someone drops the class you want, and it automatically enrolls you.

If there's a class that you want to enroll in on sis, but that class is full, first put that class in your shopping cart on sis. Then, press this browser extension which will continually refresh the page and once someone drops that class it will automatically enroll you. This works as long as your computer is on and you haven't closed out of that tab.
