Multiuser Flash Chat application! Please, Please, Please HELP

Hi,

I have been looking for a complete tutorial on how to build a multiuser flash chat which users can send private messages to eachother and it has a webcam function ability as well but unfortunately I haven't found any!

I am using Flash CS3 and CS4 so if anyone knows a good and complete tutorial regarding this chat application I will be for ever grateful if you you could share it with me.

I also purchased a Flash chat app from flashden the other and you can view it here: http://www.date-me.eu/teststst/chat.html

what I have been trying to do with this is to create a function for the users so when they send private messages to each other, they will be able to start a video chat (webcam chat) with each other in the private room.

I have created several webcam chat applications which I tried to integrate into this text chat application that I bought but I have been facing some difficulties!

The last one I created is already on that site I've shown above and you can log-in twice with two different usernames and send PMs to the other one and test the app...

The issue that I am facing is that when I try to publish video/webcam, the chat will log me or the other person out automatically. very strange!


So just to cut the story short, I thought if I could find a complete tutorial on how to create a chat app with the functions mentioned above then it will save me time!!


I will be grateful if you could point me to the right direction and help me out on this as I am stuck very badly on this.


Thank you
Regards
