We have 22 web based courses. We've gotten about 33,000 hours of utilization out of those web-based courses, and about 1900 graduates. If they were taught in the classroom I'd have only a handful of graduates today and somewhere in the neighborhood of 1000 hours of training at the most, but only if we were able to make the investment that it would have taken to get the instructor around to all the students and get the students to the instructor.
