I think you're posting and or asking this question in the wrong section. You do realize that you've joined a community full of people who play Animal Crossing: City Folk [Let's Go to The City], right? If you haven't realized that much yet, then I regret to inform you that you've really gotten off to a bad start here.
Any who, if you want to play the game with someone via Wi-Fi, then you'll want to visit 'The Gate' section and post your friend code there or something.
