Be nice. Or else.
Would you mind giving me one? mbavio at gmail. Thanks!
Yeah, it makes sense. They could also pay for future updates, something only given to "supporters". That tip was for free, next one you can pay me what you want. ;)
Looks neat! Also, I find business model you have chosen an interesting experiment, do you expect people to pay after they have read the course?
