not exactly moodle - I had edited my first post to say that I guess I'm looking more for an im thing than a chat
it's kewl - it's not completely necessary - this site is currently using yahoo but that's a pain in the butt - you have to create an account and then you have to request to be added and blah blah blah
I'll let him know that if he wants a real solution that he'll probably have to pay
thanks for your help!
