That's not quite what he's looking for... he's asking for an actual Japanese BBS where Japanese people ask questions/share information about English. Unfortunately, this forum (Japan Forum) isn't a good place, since the population of actual Japanese people who post here is roughly around 3.

I tried Google myself and Yahoo.co.jp, I found a few results there but not a whole lot. Searched with the term 英語 BBS.
