Crunchcourse is a free website that might be of use to people trying to learn things outside the normal classroom setting. It aims to get together groups of people interested in the same topic and use our social instincts to motivate us to do the work.
It is in its early stages. If it proves useful, it might be useful to standardize on it as the place to learn the various prerequisites that lesswrong has.
