1)  Add a "std_footer" sub to the setup file.  It needs to return (note: NOT
print!) a block of text that should be appended to each message as it goes
out.  For lists that don't need a footer, just have it return ''.  As an
example:

sub std_footer
{
return qq~

2)  Add the following lines to the mailing_list.cgi script in the section
marked "Do A Mass Mailing".

# PK:  Use the new std_footer sub in the setup file to add a standard footer
to the email

     $form_data{'comments'} .= &std_footer();

# END PK MODS

It should come after the following lines:

    if ($form_data{'subject'} eq "" || $form_data{'comments'} eq "")
      {
      &admin_error;
      exit;
      }

and before the while(<DATABASE>) loop.

That's it!
