Ning 2: Can I inject HTML code above individual groups?

[Steve C]

 I want to put ads above individual groups.

Jen showed me how to put text above forum categories years ago and it works perfectly—thank you, Jen! This is an example;

<!--Add Text above Is This Autograph Real? Category-->

<script type="text/javascript">
if (window.location.href.split('forum/categories/')[1] == 'is-this-autograph-real/listForCategory') {
x$('.xg_headline .tb h1').after(
"<b>Get free autograph authenticity opinions from collectors and professional members.</br></b>"
);
}
</script>
<!--End Text above Is This Autograph Real? Category-->

 

Can I put it HTML above individual groups too? If so, how please?

Thanks,

Steve
