Ever been on a site and you can't tell what are URLS or which one's you've visited? Can't tell which items you've dugg on Digg because everything is the same color? Well this will force all the URLS to be underlined, red for unvisted, blue for visited, green for links you are hovering over and Black for a link you are clicking. If you remove the comment marks /* */ from around background-color you can change the background of URLS also.
