Another thing remember
For a majority of us, Memorial weekend is already either planned far in advanced or we have family we need to spend time with or it's the one time we get have some time to get a breather from life or (fill in the blank). So to occupy that with a class, although very informative, simply does not jive well with a majority of our schedules. To have an online tutorial that we could purchase, would surely increase viewership and the reach would be much further.
I for one know with 100% certainty would purchase a tutorial set if made available as holiday weekends are sometimes occupied with non car related events. This way, I can watch it in stages, go tweak and watch the remaning balance when time is made available and I am not restricted to a permanent window. This was, I can simply replay or review a segment that wasn't clear to me on the first go around, or simply have it for reference.
My 2 cents.
