it seems rather good as it is.. i'm happy to see the encoding method is EUC :) i can see here and there few generic messages that was left in english and other things that can be done too.. i would be happy to help. i'm already helping nowee with the "pegasos-nippon" site atm and, with my studies i'm a bit busy, but in spare time it's ok.
you can explain me in detail? let's see that on irc, ok?
