title: CMS for User-Generated Content?
body: <p>I'm developing a user-generated content site.</p>
  
  <p>Note it's not a blogging system, forum, wiki or any of those shrink wrapped things.  It'll have it's own specific forms and content niche, so I'd like the power to tweak everything basically.</p>
  
  <p>The method of authenicating users will likely be 3rd-party ie open id, facebook, twitter, etc.  So the system would need to allow me to hook into another api for this purpose.</p>
  
  <p>Anyone know a CMS built for user generated content like this?</p>
