I wonder if the folks who've already started the course could say a little more about how the course is executed.
Rick, you say that the course is served up in 4-hour segments a week. Are they only available for a limited amount of time (hours, days, the whole week, the whole course), so that you have to stay on top of it, or can you go at your own pace (faster or slower)? Obviously to get the most out of the question and answer sessions, you'd want to stay on top of it, but sometimes things come up -- I'm wondering what the implications would be if you were "absent" for a couple of weeks.
Does successful completion of the course involve assignments of some kind? I'm guessing that some kind of design project is involved at the end... are there weekly assignments?
In general, I guess I'm wondering how "flexible" the time commitment is...
