posted message: To help everyone in getting through their first lessons I'm writing a series of blog posts with explanations and tips. The first of these talks about the four different types of lessons you can build and what their strengths and weaknesses are. It is up at: http://blog.wikiotics.net/2012/09/building-a-lesson-the-lesson-types/ Feel free to ask any questions either on the blog on here on the course pages.
