My God, man, don't you have classes to teach?
They're probably e-classes nowadays.
Oh, don't get me started. I've had to take several of those horrid things, and the amount of learning that takes place there is minimal. Usually the students are rather lazy, and the assignments are mostly busywork, since it's next to impossible to have a good discussion online (I had one class that did achieve it once, but never again). I don't want to teach one, ever.
