I was wondering if the JFBCFan load type is Ajax or via page refresh?
So, if I am on a site, does the JFBCFan module update if a Facebook post has been issued, or do I have to refresh the page to see new Facebook posts?
The Fan module loads an iFrame to Facebook. That iFrame is completely controlled by Facebook. Right now, it doesn't automatically update and the site would need to be reloaded for any updates to appear for the user.
