Help others start non-profit

While i love khanacademy, i would like to know how one goes about starting a non-profit if you don't mind sharing your story i think it would be of great value to the community. I asked many years ago for this place to create a wiki for anyone to make courses (this has not come). While i can see why this is not of great importants to you it is to me and i think other might have other things wich would benefit benefit from having such a course.
