I know, that already 2 chatsystem with UUB.t integration exists (jIrc and Raidersoft). Both are different in many ways but both are not free to use (Raidersoft is free in small version).<br /><br />Now I found this: http://phpopenchat.org/<br />You can set up a chatserver an your own server an handle all as you like. Integration for some boards are avaible, but not for UUB.t<br /><br />Maybe someone find it usefull and like to code a integration for UBB.t

Raidersoft does offer a free version though, I use it all the time and never have any problems <img src="http://www.ubbdev.com/forum/images/graemlins/smile.gif" alt="" />

As I read, Raidersoft is not free. I found this: "If you don't have the paid version of raidersoft, you just need to turn off the automatic authentication - as the free version of raidersoft doesn't support it." in a notice from Josh in a comment to the integration.<br />Also both chats use external server. My suggestion setup a own server with total control.
