I tried to post on that one but got this message,

書きこみが終わりました。

画面を切り替えるまでしばらくお待ち下さい。

Translated as...

Writing is over. Please wait until you switch the screen.

I guess it's a 'wait for redirect thing' but nothing happens.
I know no-JP IPs can post there as there are some obvious /b/tard posts.
