Q: This book is a collection of two books, so you basically get the first half for free and have to buy the second one because they are not in order. This makes me quite angry. It should be stated immediately that this isn't just an inconvenience. For example, if I want to know some information about how to implement data encryption with Mailvelope, I'll look it up online using [...] first, then try again by finding the URL with mailvelope.com/learn? And that's it.

Q: It's fine but very cheap. It won't fit in a standard book. You have to remove some pages prior to putting in.
