Robert, the lines you specified are already in the css. The problem lies elsewhere. I worked with WILL on the styling of the site and it's a bit more work than just adding a few lines to the css file. The problem is that if you add a random link without tags like so http://www.google.com , the link appears in yellow (the default link color). However if you use tags , it appears without an underline http://www.google.com. We need a solution that solves both situations. Unfortunately this requires more work than just a few lines in a css file.

For now, best thing is to use the solution Paulius mentioned.
