chat thing still buggered?

Hi all.
Just wondering what chat systems you guys use? I was going to use phpMyChat but i cant seem to configure it all with ease.
I am looking for one that:

- is free
- easy enough to install
- has censors
- has private messages
- has admin (and prefferably, but not needed) and moderator functions (kick being the main one)
- is customizable to use with my current css file.

Any ideas?
ta.
