Prince is a valuable contributor. He is an awesome developer, developed couple of add-ons (https://addons.mozilla.org/en-US/firefox/user/Prince3333) which are helping thousands of users for better experience on Firefox. He is also a Webmaker Mentor, and helping Mozilla in our vision of a web literate world. I have seen him doing very well in MCR community also. Good luck Prince :)
