Book for Questions and Answers

I've had people commenting/messaging me either directly or in the comment section. One main thing that have burdened me for a long time is the fact that I cannot reply to them due to my email. It primitively asked me to verify and once I did it still would not be verified. Moreover, I made this book to straightened up that specific problem.

As of now, please comment here for questions and other things like chatting! I will reply to all of them once I've seen them.
