title: PHP: Facebook / Twitter Integration
body: <p>I have a CMS built in php and I'm looking to add Social Networking integration to it. I basicaly want to pre-populate the comments and contact us forms with the Facebook/Twitter information of the visitor if it's available.</p>
  
  <p>Is there something reliable already built and tested or should I start from scratch?</p>
  
  <p>Thanks.</p>
