Forum/Chat/Newsletter

Ok .....so I need a PHP / fantastico expert. The website in question is [login to view URL] I made this website ..but I had hired someone1 2 help me with the PHP. We had decided that later we will install forums/chat/newsletter in it but the guy who had helped me back then has disapeared into thin air. Sad as the situation maybe I am forced to hire some1 new . Now here is the tricky part...i want forum/chat to be such that it should REQUIRE login and ..it should use the same database which is being used right now for logging into the website. I have fantastico installed so that shouldnt be a problem or if you are used to some other good script that is fine by me 2. I normally hire non gold members as well but this time ..I cant because ive been burned once already. Lowest and best bid wins. Best Regards Anando
