This is the code that makes Nick's entries look the way they do:

TD.nick {background-color:#add8e6; font-family:verdana}
TD.nickborder {background-color:#6666FF; font-family:verdana}

CSS allows me to customise a few things, but if you tell me the font, and colours (hex values please) that you want, I'll do it. I'm not gonna guess.
