Re: Facebook-Like-Chat Plugin for Buddypress?
Because this is the thread about it I found 2 more that were not mentioned:
http://www.123flashchat.com/web-messenger-chat.html ( i dont know if it integrates with buddypress)
and this developer project:
123flashchat looks interesting it says:
var username_123webmessenger=<?php echo $_SESSION['user'];?>
to integrate it uhm have to lookup for buddypress/wp what the current logged in username is.
