Ok, after some digging, here is what I have found. Please confirm this when you can.

1. My program adds a row to CuteChatLobby, IsPublic = false, IsEnable = true, IsHidden = true, AllowAnonymous = false, ManagerList = '1,2'  where the list values are the userid numbers from the CuteChatUser table, comma separated.

2. The missing info was the ManagerList field, described in item 1 above.

3. The url should be something list this:    http://localhost/Chat/CuteSoft_Client/CuteChat/CH_MainForm.Aspx?Location=Lobby&LocationId=3

Hope this is correct and is helpful to others...
