Why can't an ivy league school make online registration work?

I just need to release a bit of frustration- it's really lame that Notre Dame has so much trouble with their online registration. Actually, they have a lot of trouble with anything online. But their online registration is especially messed up. I was supposed to be able to register for classes back in November, but you can't register for a class unless you have special permission by either the instructor or the department. Most professors tell you to wait until the first week of classes to register so it can be handled all at once. So, you show up for the first class, put your name on a sheet of paper, the teacher takes that list and gives it to another professor in charge of manually entering in each student into the computer system, then the student goes and registers online. I honestly don't know why they won't let you take any graduate courses without special permission (graduate students also can't take undergraduate courses without special permission). The whole process is unnecessarily convoluted. By the second week of classes I should be registered for my classes.

My other complaint is why do I have to have a professor signed add/drop card to return a textbook I bought from the ND bookstore. It makes no sense! I have the receipt! Another gripe is the enrollment issue. You have to enroll every semester; this is different from registering. Enrollment is a signed document telling ND that yes, you will be attending the university that semester. Even if you somehow managed to register for classes, you still have to fill it out. Otherwise, you are thought to be a dropout and are booted from the university and have to reapply to get back in. Notre Dame's system is in dire need of a makeover. Who knows, maybe it's 'tradition' that makes them keep their crazy system.
