"You can viralize any post or page in your
WordPress blog, asking your visitors to refer at least a
certain number visitors before they can see the full
post or page! Your visitors will not get access to what
you offer them until they have referred enough friends
or other readers to your website!
You can promote ANYTHING you want! Pictures, videos,
files, guides, secrets, just about anything!
It is VERY EASY to use. Just activate it, and you can
viralize any POST or PAGE on your WordPress blog..."
