That's an Issuu thing. But Issuu can be opened up via Facebook. Hit log in and then select Facebook connect. It won't put anything on your FB timeline (I've done the FB connect thing and can attest to this).
The sign up part is because it's over 18 - you need to click OK when that comes up and then you can read. Sorry for the hoops but it's because of images, and a bit of language, that are MA.
