Contest reporting/tracking system

Summary: We are looking for a data reporting/tracking system for an online contest based on real-world action. It is necessary to keep track of actions taken as reported by users, and calculate a score for each user based on the actions they have reported. There are several different types of actions each of which are worth a different number of points. We need a moderately flexible system which will display actions taken and/or points in several different ways. Required: Capture form submissions to MySQL database Key by email address (no authentication) Score for each user determined by all submitted actions worth varying amount of points Display top users by score Display top schools by score (of all affiliated users) Admin can delete fake or erroneous submissions Admin can add additional types of actions Highly Desired: Dynamic AJAX form allowing submission of multiple actions Session/cookie to remember supporter information Display score for current user Dynamic output of top x in category x (i.e. Most Letters by State, Most Calls by School) Desired: Salsa/WiredForChange integration (track referred online actions) Display in a Wordpress template Facebook Connect integration
