Subscriber area
Access is by invitation
The sources, the changelog, the digest archive and the receipt in subscriber wording are for subscribers the operator has invited.
Subscriber sign-in
If you are a subscriber, use the username and password the operator gave you. If you have not been invited yet, ask the operator: access is opened by hand, never by self-registration.
This service holds no personal data about anyone. Your agency signs in with a username the operator made up — not your name, not your company, not an email address — and a password stored in a form nobody can read back. Which agency a username belongs to is the operator's own note, kept outside this service.
