ok i have searched the internet far and wide, all i want is to put the simplest chat room on my website, just like this one.

i realize that i could just link to this one but i want to change what it says at the top and the bg color, but nothing else. anyone know how to get this on my site?

The link you have here does not work so not sure what you want exactly.

That looks like a ShoutBox script. You have 2 choices on the code used if you want to host it on your site, Javascript or PHP.
