The "special site" from ALLFOR916 that was to open on September 3rd seems to be a report gallery with many pictures of the people who went to the caravan. They also are displaying an Instagram feed of all who've posted with the tag.

Fanspace has also updated the video diaries up to Osaka on August 30th.
I like that each video plays a different namie song!
