There had been a black hole that folks were getting stuck in when they signed up for the newsletter. I fixed it! Now, when you sign up for CatLover Magazine, you get signed up. That means you get the Free eBook, too. That was what told me something was wrong. I got 2 emails in 2 days about not getting the book. I fixed those, and then went about fixing the problem.
So, if you sign up for the newsletter, you will now get the opt-in message in your inbox. When you confirm, you get to download the eBook. That's the way I set it up, but it wasn't working. Now it is.
