I tweeted, tried to sign in with twitter which didn't work, then eventually created a standard account via email/pass to get into the content. The majority of the content is either a direct copy as cited or in reference to a post on a different site [1]. Not really ground breaking information, other than an Excel worksheet with mildly helpful formulas relevant to the topic.
