as far as i know, kanon has been translated by Haeleth for serveral years, so far he has finished 80% at least so i dont know if you are with him, or you guys are doing it yourself. i dont know if you know here:
http://www.haeleth.net/kanon.shtml it seems he wont release his translation because lack of offical premission but he did almost finish the translation. btw, are you translating anime(subtitle) or the game? air project was dropped a couple years ago, but 1/5 are finished, i believe you can find that incompleted patch online somewhere, but anyway, if you pick it up, that is a great news. and may i ask who else is translating Clannad into english? do they or you guys has website? thanks.
