It is very simple!
What I'm talking about:

When you hover the text(link) it glow!
1. Navigate to your Admin Panel->Display->Pictures and Colors->Colors->CSS Stylesheet
2. Add this code:

Code:

a.forumlink:hover {
letter-spacing: Xpx;

a { text-decoration: none; }
}
.forumline .row1.over:hover {background:url('') right bottom no-repeat;}
.forumline .row1.over:hover {
background-color :your color code ;
}

In "letter spacing" you can choose the space between the letters when it hover!
You can add background image to the letters too.
