Too good to be true?

Okay, this isn't like me, but I signed up for this marketing scheme and now I'm not sure what to do with it. It was free, so I don't think there is anything to lose, but it is very vague as to exactly how it works. I found the link on a fellow bloggers site so it must work because I clicked on it, right?
Perhaps! Perhaps not!
Does anyone out there know anything about this plan? And the best way to make it work?
Any input would be greatly appreciated!
