I'm sure that title doesn't totally explain what I'm needing and looking for. I'm working on a chat box for my site. I was thinking of ways that I could build this chat box and one of the things that I thought would be cool is to not have to refresh the page whenever someone enters another line of chat. I simpy want whenever someone enters another line of chat it would auto display the new text on the screen without having to refresh the page. I was also thinking that it would be cool if it has a fade in effect kinda like (not required though).
document.write("Oh yay, look at my pretty text. :)");
