I'm looking for active forum communities of specific anime, but I can only ever find a handful? So I was wondering whether anyone else knew any forums for specific animes? (It doesn't matter which anime, but it can't be a general anime forum)

These are the ones I know of:
Naruto: link and link
One Piece: link
Bleach: www.bleachanime.org and link
Rurouni Kenshin: link
Fairy Tail: link and link
Kuroshitsuji: link
Gintama: link
Fullmetal Alchemist: link

and not really an anime, but vocaloid has one too: link


So does anyone know anymore? If so, please add to the list, thanks :]
