It has recently come to my attention that helloproject.com is pretty delete-happy. Once stuff is no longer current, it's often gone. Links to information about past concerts will go to 404 pages, as will now all the Berryz Koubou helloproject.com discography links (though their up-front-works.jp counterparts still work). Most of it gets caught by archive.org so we can generally fix the links to display the same information, but it is something to keep in mind.

It also means it's harder to even find a link to old stuff, since all the links to the information will be removed from the site. I once worked around this by finding a broken link that still existed on a fan page, but probably trying to view an archived version of helloproject.com from the right time period would be a way to find that information too.
