If you need, I can provide QQ numbers (register them for you) for testing this, and I'll make myself available for testing as well, if you reply in this thread that you'd like me to do so, I'll provide a contact email or messenger ID# for a different service.
Anyway, it seems that beta 9 can connect and send messages to the QQ system, but not receive messages. When I tested this I was using the server:
sz.tencent.com:8000
Many thanks for your work on this excellent project, I'm amazed at the number of things done in beta 9, and I know this stuff isn't easy. Having QQ support work in Adium will definitely get me to switch off of iChat and iQQ, and anything I can do to help you guys in that effort, I'll be pleased to do, since the inclusion of this protocol is so important to making Macs more accepted in China.
