title: Facebook like button: hide text
body: <p>I just added a Facebook like button to my website, just the most basic one, but you can't select to hide the "Sign Up to see what your friends like." text.</p>
  
  <p>Because the area for the button is so small, I don't want this text, as it overlaps with other text next to it.</p>
  
  <p>Is there a way to hide this part?
  I basically just want the like button, with the same functionality.</p>
