How do you create such a page?

I found this page that seems to be very efficient for getting more fans:

You first have to join, then to invite all your friends, and only then you can see the CPA offer.
Any idea how he created it? I looked around for a little bit but couldn't find any tab that would work that way.

Thanks!

edit: also he has some cool fake comments on that page!

Look in the BST section here at BHW, Carolina was originally selling the information but she is now giving it away free. Ask her for a copy.

this page is so viral
