Hey there! Great work. I think you should actually try and gather money or a community around the project, since it seems like it has a LOT of potential to be something big. I'd give money for a Kickstarter like this!
That is very generous of you, and I'm extremely grateful for such dedication towards this project. I will tell some friends that could be interested about it and they will definitely pay at the very least $1, no sharing for free :)
I wish you good luck with the book and I'll support you until it's over!
