I recently found this site I dont know who made it but its just for अवतार fans. आप can buy bending and other things and play games. Its very cool and i reccomend it. The only problem is आप have to be using गूगल chrome for the chatroom to work but गूगल 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, या tribe!
