Ravens PHP Scripts - Block to display news sent by online members

I created a block that displays the stories submitted by the members that are online on the website on that moment. So, if there is logged in user1, user2, and user3 this module will display all the stories submitted by user1, user2 and userr3. This is good because users return to your website and stay on it longer, to have their stories featured. The block is working on my website homepage: Oportunitati de afaceri si lista coduri CAEN and you can get the code here (see my second post on that forum for the working code).
