I recently found this site I dont know who made it but its just for 阿凡达 fans. 你 can buy bending and other things and play games. Its very cool and i reccomend it. The only problem is 你 have to be using 谷歌 chrome for the chatroom to work but 谷歌 chrome if free and guick to download, so its ok. It has few members, but its new so that will change if lots of people from here join. They even have a special firebending game and boy and girl charecters for every nation, kingdom, 或者 tribe!
