title: Looking for a easy integration PHP forum
body: <p>I'm building a website with codeigniter (PHP) and I'm looking for a forum easy to integrate with my current database so users don't have to register twice. Moreover, I need to use the same html head and styles that in my website, placing the forum inside a div of <code>&lt;body&gt;</code></p>
  
  <p>Could anyone recommend me any simple forum application for my situation? Thanks.</p>
