We're trying to archive interviews, and official creator content, as well as fan accounts from cons posted to the web. If you would like to subnit links to official content, e-mail me or send us as ask on Tumblr. You can also post links to official content on our forums.
Loopy has archived Nick.com's old site dedicated to all things Avatar: the Last Airbender. This tumble is filled with information on characters, weapons, places, animals, and official world-building information the likes of which have not been seen since the old site went dark in 2009.
