A Word of Caution!  You can also apply online at the Web sites of most schools.  Because this is a relatively new feature, though, there were problems with it last year.  Servers at some schools will overload and crash on the day applications were due, causing a lot of applicants to panic.  If you plan to apply through a school's Web site, be sure to finish your application at least a day before the deadline so you won't have to worry about the server crashing during the last-minute rush.
