Hi, I am a c# developer and am working on a web site that contains user accounts. I am trying to add a chat feature like facebook. Only direct chat is to be available like IM, a logged in user in the website should be able to chat with only logged in users. And the user can chat with only one other user at a time. If he wants to chat with another user, he must open a new chat window for him seperately. Which is exactly like facebook's chatting system. Any guides how to go about this. I am a newbie in web applications. Also, preferred language to go about his is asp.net.
Thanks in advance.
