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.
