I've been remaking the GT site, and I'm going to add a chat option for members, and I was wondering if it would be possible to be able to send it through the server.

Here is where I got the simple chat from.
http://www.ajaxdaddy.com/demo-ajax-chat.html

Ideas are bounding round my head, but I can't figure it out. Is it even possible?

Or is there a way to add a chat item like that?

Is there a way to log chat? Only chat...

Because in the chat.txt file is where it loads the messages from, I.E
shaggy | Hello

So I'm wondering if there could be a way I can update that file with new messages.

Lol, funny, GT doesn't even have a server and I'm caring about this like it's number one on the priority list.
