Woohoo! Plus this let me do one of my favorite things, which is to call to congratulate the students who've gotten an A or an A+ (generally 12-15% of the class, under our new grading system).

Note to other professors who call to congratulate students, based on experience gained the hard way: If you don't reach the student, and leave a generic message that doesn't mention the grade (particularly important if it's a shared voice-mail or answering machine), say something like "It's no big deal; nothing to worry about; just call me back please at your convenience." A student who just gets an unadorned "please call your professor" message will FREAK OUT.
