CMS addon for accountlab plus

Account Lab plus keeps some customer info in the $_SESSION variable, including the users ID in the system. Account Lab Plus has a built in function for getting info on a user that takes their ID as an argument. When an admin/client is logged in, their info is in the $_SESSION variable. I want somebody to make a php system that turns Account Lab Plus into a cms using the $_SESSION variable. I want it to support ranks using a "Custom Field" in the client info.
