I have the background done... I had to play around sorry... now I would like to know.. how do I get my forum like this .. the white around the edges of the post bit and forum categories...
Could someone tell me if this is possible?

The .tborder class in global.css

Add the background you like (for example white #FFFFFF) and then, put 1px of padding, like this:

.tborder {
    background: #FFFFFF;
    padding: 1px;
}

Thank you eNvy
