I tried sending an e-mail via their web-form to ask about this document on 10 August, but the e-mail bounced. The form tried to send to [email protected], but returned an "access denied" error:
Mail delivery failed: returning message to sender - [email protected] - Gmail

I might try their phone number sometime.
