The "Editor=" keyword defines who can post to the list directly (without
going through the editor) and who gets a copy of the messages submitted
by normal subscribers, for approval. It is not an addition to the list of
subscribers, and indeed most editors are not interested in getting a copy
of what is posted to the list since it always comes directly from them.
When an authorized editor posts a message, it is not sent to the editors
because it does not need to be approved. Just subscribe to the list if
you need a copy.
