Clone of wishlist.com

This is a project where we need to clone [login to view URL] with the following improvements: * The price on the photo must not be showed unless the mouse button hovers over it or when clicking in the photo to see it full size. * By tracing the IP address of users, a reminder has to pop up every once in a while to recommend users the installation of the bookmark * A percentage of profile completeness, the more information in a user's profile, the nearer to 100% completion, showing which parts are missing * A leaderboard, where users are ranked. Each user accumulates points for: * Inviting new users * Grabbing new products * Commenting photos * Tagging friends * Flexibility is required in the leaderboard, we have to be able to create new paramenters and modify existing ones * Email system that collects each user's and his /her friends most famous interactions in a weekly email digest
