Hi Hidetchi,
I understand the value of menjo in material it is presented and in high standing of people who sign it, but does menjo have significant practical value in shogi world? In example, are there tournaments requiring certain Dan level, which can be proven by this menjo?
It seems this certification isn't very robust and can be exploited, because it is possible to become eligible not only via over the board play, but via newspapers, online quizzes and online play, where it is hard to ensure no side help is being used. Or am I talking about thinghs unthinkable? :)
