7.1.2 MODE READER

    MODE READER SHOULD be sent by any client that intends to use any
    command other than IHAVE, HEAD, STAT, LIST, LIST EXTENSIONS, or
    commands advertised by the server as available via LIST EXTENSIONS.
    Servers MAY require that this command be issued before any other
    commands are sent and MAY reject any other commands until after a
    MODE READER command has been sent.

    The server MUST present a response using the same codes as the
    initial greeting (as described in section 7.1) to indicate its
    ability to provide reading service to the client.

    Clients SHOULD wait for a response to MODE READER after sending this
    command and SHOULD NOT send any additional commands until that
    response has been received from the server.

    Once MODE READER is sent, IHAVE (and any extensions intended for
    peer-to-peer article transfer) MAY no longer be permitted, even if
    it were permitted before the MODE READER command.

    Servers are encouraged to not require this command even though
    clients SHOULD send it when appropriate.  It is present to support
    some news architectures which switch between modes based on whether
    a given connection is a peer-to-peer connection with another server
    or a news reading client.  It is preferrable instead to accept
    peer-to-peer connections on a different port and to assume that
    all connections to the standard NNTP port are from news reading
    clients.

[Responses and Examples unchanged from the current draft.]
