title: Communication between iFrames?
body: <p>How can you make two iFrames talk to each other?
  For example I was a element value off the 2nd iframe and the 1st iframe has the display element on it. I need to get the value off the 2nd frame to the 1st. How would I do this?
  Don't say use cookies, cause that will hurt with massive sum of data.</p>
