Khan Academy Ranking System

Hi Khan Academy community and staff, I read a post about this specific topic and hoped to revive the idea (the post was last updated a few months ago, thanks carol). I don't have all the details sorted out right now, but the implementation of a ranking system to incentivize learning on Khan Academy would be a great addition. It'll encourage students to log in daily to keep their ranking, and in turn, lead them to be brighter. I, personally, am very competitive, as I'm sure a lot of other people on this website are, and a system like this would push me to be more productive. As a chronic procrastinator looking to take the SAT in December, I find every excuse to leave my daily question quota to the last minute. Overall, a ranking system would motivate me, and many others, to start integrating Khan Academy into our daily lives. Sorry if this suggestion has gotten stale. 

Also, custom backgrounds and banners for our Khan Academy dashboards? Thanks (:
