Last wednesday a collegue was trying to integrate his facebook friends within a site built with Joomla. He was having problems with the code, ...and i asked him, why don't you use a module for that??.
Yeah, joomla has modules for everything, absolutely everything. I like to digg into joomlabyte where you can find from free to commercial modules for joomla. ...and here it was, the Facebook Fans Joomla Module.
