For example, if I want to chat with user "rainsong", and I konw his userID is 2,and I want to use "IM_ChatForm.aspx?UserID=2" to chat with "rainsong". and how to config it!  I have tried to use "IM_ChatForm.aspx?UserID=2" directly,however a script error appear ,that is "error: CuteIM is null or not object code :0".

      Thank you for your help!
