I want to thank everybody that participated in discussions - also to subscribers that sent "thank you's" and words of encouragement. I'm a full-time Microsoft Certified Trainer at an IT college during the day, where I teach various programming languages and software development technologies. So, I only develop these videos lessons after-hours and in my free time - sometimes well into the night and early-morning hours.
YOUR words of appreciation and encouragement is what is driving me to want to continue with this service. YOU are the reason why I enjoy sharing my knowledge and skills - and for that, I THANK YOU!

Like the lessons in Chapter 1, I will publish these videos on a lesson-by-lesson basis - in other words, when I'm finished developing a lesson, and after testing it, I will load it on YouTube. I try to complete at least one lesson a week, but sometimes you may have to wait a little longer. The lessons in Chapter 2 will also be jam-packed with easy-to-understand analogies, high resolution graphics and animations, and fun-to-follow practices!
 
If you have not subscribed to this channel yet, I hope you will do so immediately - please join me in all the fun!
 
All the videos in Chapter 1 is available in the following playlist:

Kind regards
