Hello all !
Alright, I know I don't have a lot of time recently to do ebooks, and soon I plan to go to reduce the speed even more.. Hurt right ? Actually I've just started to develop the next version of the website, if I make it right, it should change the way to use it... but it will be hard to make. And RL work didn't decreased yet ^^'
For now enjoy this book, because I enjoyed making it !
