(Message Security)
 ------------------

 Subcommands:  (G) (R) (S) (N)

               (N)one means that the message will be open for all to read.

               (G)roup allows assigning a password to the message which
                  only other callers who know the common password will be
                  allowed to read the message.

               (R)eceiver makes the message private to all except you - the
                  person leaving it - and the person to whom it is addressed.

               (S)ender allows you to assign a password to the message so
                  that only you can kill it later.  This prevents the other
                  person to whom the message is addressed from killing it.

 Description:  When leaving a message to another person various security
               levels are available to allow "protecting" of your message to
               insure only those who you want to read it can.

               Note that you can NOT assign (R)eceiver protection to a
               message which has been addressed to ALL.
