You just log in every day, answer a question, which gains you some points into redeeming them for free stuff like electronics (laptops, video games, mp3 players) and fashion items (designer jewelry, shoes.)
The sites not currently open but in a month or so, you can play games to earn points and they'll be way more prizes and things.
Just letting you know :)
if you want one, just leave me an email and i'll send one right away. their invites have been iffy and lots of site maintenance but it should be great now.
