The latest is that Japanese fans can now enjoy an official Death Note Facebook page. It's been launched by Shueisha, in order to relay Death Note's 10th Anniversary news and events.
Unfortunately, I don't speak Japanese, so my best efforts with reading its promotional entries will necessarily involve Google Translate. Having seen what that program does to Welsh, I'm not filled with confidence.
If you CAN read those entries, please do report back. We'd all love you forever.
