I've downloaded and tried the Want button for Facebook but I still couldn't understand what the use for that button! OK that what I did :

- when I clicked on the button Want "to test " it opened the log in page for Facebook, So I logged in.
- On my Facebook notification I found notification from WANT Button: thanks for joining Want!
- Now If I click on that message I stay on my Facebook but with a blank page in the middle ! why is that ? is it from the script or from Facebook, I was expecting to see a list of products that I clicked on their Want button but that didn't happen !

Anybody had the chance to use this button and how to use it ?
