Add members to autoresponder

I am using phpLinkDirectory for a new housing exchange program. At the moment there is no way to contact my members, and it doesn't look as though there will be any implementation of this in the near future by the programmers. What I need is a small modification to add new signups to my autoresponder eMail address so I can keep my members updated. **Edit:** Just an update to clarify...all I need is a small addition to the sign up part of the script so that when members sign up, an email is automatically sent with their name and email address to my autoresponder email address, i.e. mylist@mydomain.com. This email address takes care of the rest. :-) I apologise if I haven't explained myself properly. :-(
