i have seen methods of setting one up using Java or a flash link into a forum entry but perhaps Admin have a method on the site where there able to set one up but just haven't done it. Admittedly there are issues with setting up live chat, such as monitoring etc but i believe a lot of the external addons have a built in monitoring system. i suppose it would have to be asked if there is such a need for a chat room, get some feedback before trying, this ones purely up to the Admins to decide on.
