I should add that you can add the plugin though the admincp manager, add new plugin too. Just copy the existing 'show the mood menu in all pages', give it a new name & in the code swap 'header' for 'navbar' so that 'search html' part of the plugin looks like this;
Code:
$search_html = '".(($show[\'pmwarning\'])';
$vbulletin->templatecache['header'] = str_replace($search_html, fetch_template('vmoods') . $search_html, $vbulletin->templatecache['header']);
