Activity Stream on Profile Page

Ok. I read the guidelines and also went throught all 5 pages of support questions but cannot find anything on the activity stream on profile page. I'm using Windows 7 and Google Chrome and the ONLY thing that isn't workin for me is my activity stream. I've been on Pixelscrapper for just about 3 weeks (joined at the beginning of August). But my Activity Stream still says: "Soon this page will display a stream of this user's activity. Stay tuned!" I've filled in the Profile Expectations and also did the Introduce Yourself post. Am I missing something? Or doing something wrong? Please help.
