Duel version 2.0

Based on the successful Duell 1.0 project, we're going to rewrite the old project using more client-side scripting to make it even dynamic and scaleable with a lot of more features/adjustments along the way, including the system which allows users to reply by email without going to the website. The new version is to use full power of HTML5 and client-side MVC scripting using ExtJS 4. Full spesifications will be supplied on request.
