I think at the end of the day it all comes down to what the owners of the forum want. You just simply can't argue with that. The owners are English speaking only people who reserve the right to enforce whatever restrictions on the site that they feel. If the site was run & owned by some Japanese then it probably wouldn't surprise you in hearing them insist upon the posts being in Japanese. You have to be very "Diligent" with this sort of thing, I tried to be in my first post, obviously not hard enough.
