The forumdisplay template is in Admin > Styles & Templates > Style Manager > (The style your using) > Forum Display Templates > and edit FORUMDISPLAY.
I added the lines in the body under here:
Code:
<body>
{vb:raw header}
{vb:raw navbar}
<vb:if condition="$announcebits">
<ol id="announcements" class="announcements">
{vb:raw announcebits}
</ol>
</vb:if>
I think this is what you mean?
