Add An Address
A subcontractor whose email lands here may self-register through the normal sign-up page even though their address is not on a corporate domain — the same pending-approval flow every technician goes through. This is a SECOND, independent door alongside the corporate domain list; it never widens who a corporate email can be, and a corporate domain is never added here.
Allowed Addresses
Revoking an address only stops a NEW signup through this list. It does not disable an account that already exists — an address that already registered keeps its account open regardless of this list. To lock out an existing account, set its Position to "No Longer Employed at 3S" or disable it in User Management.
