Hi, just launch my first product at GumRoad

Hi friends, I built a screencast about building fun project with PHP. It's a fun thing to be able to share my knowledge while building something and it's the first time I use Gumroad. If possible, I will share update about things which can be improved later on.

I created this screencast because I wanted to share about knowledge I gained while working with PHP.

If you don't mind, would you take a look at my screencast? Are there things which can be improved based on the screencast?

Thank you!
