Added a few things:
- You can now sign in on the mobile version, it'll sign you up automatically through cookies the next time you visit
- If you're signed in and already downloaded a few books, you'll get personalized recommendations
- You can submit comments on books/authors/lists
- At the end of our Mobipocket books you'll find a link to post a comment about the book that you've just finished reading
For those of you using the guide on the Kindle, I also recommend signin up on the website. This way your downloads will be logged and you'll still benefit from the personalized recommendations feature.
