Add this to your headers if you don't have it:
<script src="jquery.js"></script>
<script>
function text_after_forum(forum,text) {
$(function() {
$("div.tborder:contains("+forum+")").after(text);
});};
text_after_forum("CATAGORY","TEXT");
</script>
Footers
This is just a random code I wanted to make, I doin't know why, just felt like it
CARAGORY = Put the catagory name you would like the text after
TEXT = The text that goes after the catagory, If you would like, you can use HTML.
