Hi

I need to add a real time web base chat system to my website. I need advice on technologies.

The existing website was built by ASP.NET, C#, MSSQL 2005.

I viewed some live cam chat or flash chat which is cool.

http://www.123flashchat.com/demo.html
http://www.everywherechat.com/chatnow.php
http://www.flashcoms.com/products/one_to_one_chat/

Should I use Flash to build it?

How should I do it?

Is there any online tutorial with full actionscript code?
