What should I read next? 

i'm very confused...how do i sign up?

Start by typing in the title of the book and searching for it. Click on the title when it comes up, and at the bottom of the page, there should be a place to enter your email address....click on 'Register', and the book will be added to your list. From there, you can add more books to your list. Once you have built up your list, you can click on 'Show similar lists', which will show you other people's lists that have a lot of the same books as yours, or you can check the boxes next to one or more books on your list and click 'What should I read next?', and you will find similar books in the same genre.
