Not really for the general public, but it can be found by the general public. They really should of and could have done the site different, but they did not.
That link can be found with search site and you don't need the password for it.
Not that the username and password makes much difference as it's the same for everyone.
Also there are site that I have found the username and password posted, so I don't think it's much of a secret anymore.
Not much different then the servicematter.com site info.
It's also nice to have the manuals on local storage for personal use though. I have around 1500 service repair manuals on my HD.
