title: Facebook, possible to hide 'unlike' button once user has liked a website?
body: <p>I thought i saw some code yesterday but i cannot find the link now. I wish to present the user with the like button if they havent already liked before, but if they have liked, then to hide the unlike button.</p>
  
  <p>If memory serves me well, i thought i saw the line 'fb-connect'?</p>
