On 'mastering via teaching', this is exactly what we're talking about! The formal sites look great, but it can be a bit intimidating to a hobbyist with a blog who wants to teach knitting.

On the homepage. You're right. We need a 'this is what it looks like' front and center. This is early on still and we just finished the product, so next step is to make a 'how to make a coursecraft course' course which will also serve as an example of what a course looks like/what you can do with the product.

Thanks for the comments!
