I am citing the Avatar: the Last Airbender Guide & Forum Rules Post 6, Amendment 2:

Fanfics should not be posted here. As one user stated "This is TV.com, not Fanfiction.net." This forum is to be used for discussion of Avatar the TV show, not fictional works created by fans. Fanart threads/links are permitted (but everyone should not create their own fanart thread, one could be created for all to show off their work in). But fanfiction should not exist here in any form, as more times than not fanfiction has little to nothing to do with the show and is just baseless fan theory. Even if your fanfic does have some relation to the show, please don't post it here. (Added 12/30/06)
