need chat box for my users, like on facebook

Hi, I want a chat box like on facebook, where users can talk to each over and they must be friends before they can chat to each other, any ideas to what i need and to do

 

what kind of site are you running n did you design it yourself...

 

try phpopenchat org there are unlimited sources .my be you will get what you want easily there.other wise you can use flash chat system there are great too extra with effects

 

Flash Chat is a good one http://www.tufat.com

 

You can search with jquery library about content "shoutbox", There's a jquery plugin can do as you want.

Try: http://www.jquery.com

 

You want a general chatbox or a user-to-user instant messaging system?
If it's the second, please tell me what site/script you are running, whether it's custom or boxed etc.
I may be able to help.
