I find the classes too short, and with the number of people, too general. I think it's better if people can choose what they want to work on and pool their resources, directing their energies into what interests them most.

I'm planning to start as soon as I can get a good ten or so people interested. I appear to be close. It may be enough, where it stands. Then, as soon as the weather clears a bit and people are less prone to play.
