While I think that authors should have a right to control how what they create is used, I also know that it is impossible in this time where so many people have a computer and internet access. It is entirely possible for someone to take any book and type the entire thing into their computer and email it to whoever they want. Most of the time this would never happen because people are too lazy to go to the trouble of doing it. Still, it is possible and so I never bother to put a copyright notice on any of my blog posts, books, or videos. I hope people are nice enough to ask me for permission before they copy something of mine, but since I don’t have the money to sue them, they will get away with whatever they do with or without my approval.
