Awesome!! That sounds really cool, glad you're feeling better. drophy and I have made a couple of websites, but not public domain (which I am assuming that is what you are doing?) Good luck on the creation and can't wait to see how it goes.
Cool things to include would be a clan leaderboard that would be updated after every match, also clan websites like Valkiria said, and also a clan war scheduler or challenging system (maybe) that would allow clan wars to be arranged outside of GameFaqs. Those are just wome ideas.
