Ajax Chat like Facebook(repost)

I need a chat function adding to a website. It needs to be very simple and needs to integrate into the existing site sessions. I think <[login to view URL]> is a good start but I am happy to use another framework or example script if you have recommendations. In addition to the chat, it should also allow the user to set the status (offline, away, busy and online). The list of online uses will come from an existing database table. Current user is provided via PHP session variable. There is the strong possibility of more work on the module but I'm keen to get the simple version up and running very soon! ## Deliverables As in the summary, this is customization project. I believe a script like <[login to view URL]> just needs to be modified to work with the existing site. All information and examples will be provided for you and I am happy to help answer any questions. Should work on standard CentOS/Fedora LAMP servers.
