Only when I have personally written a bulletin, a policy letter or a SEC ED should it be signed "L. Ron Hubbard" or "L. Ron Hubbard, Executive Director".
When I have knowledge of or have okayed a bulletin, policy letter or SEC ED but have not actually written it, it should be signed "Jane Doe (the name of the actual writer) for L. Ron Hubbard" or "Jane Doe, for L. Ron Hubbard, Executive Director".
When I have not seen or okayed a policy letter or a bulletin or a SEC ED but it is published by the authority of a held post such as HCO Sec, it should be signed "Jane Doe (actual name of person issuing) HCO Sec (or other title)".
The field or public must not be led to believe that I have written or issued things I have not. Further, other people have authority, too.
