suppress confirmation file

Hello,
 
I wanted to know if there was a way to suppress the outgoing
confirmation email message when a user is added to a mailing list.
 
Our setup is as follows:
 
I set up email lists for various departments of our organization.  They
would like to edit the list themselves instead of giving me requests so
that I can edit the dist file.  I would like for them to be able to do
this themselves.  Our host gives us access to make web-based x-commands,
but these send a confirmation email out and it would confuse many of our
users.
 
Another option is to set up a password protected area and then make a
PHP file that lets the managers edit the text file themselves.  Does
anyone know of any pre-existing code that does something like this?
 
Any help would be greatly appreciated.
