En
forumdisplay_thread busca:
<div class="author smalltext">{$thread['profilelink']}</div>
Cámbialo a:
{$ratingcol}
<div align="center" class="{$bgcolor}{$thread_type_class}" id="rating_table_{$thread['tid']}" style="float:right;">
<ul class="star_rating{$not_rated}" id="rating_thread_{$thread['tid']}">
<li style="width: {$thread['width']}%" class="current_rating" id="current_rating_{$thread['tid']}">{$ratingvotesav}</li>
</ul>
<script type="text/javascript">
<!--
Rating.build_forumdisplay({$thread['tid']}, { width: '{$thread['width']}', extra_class: '{$not_rated}', current_average: '{$ratingvotesav}' });
// -->
</script>
</div>
Me gusta tu idea, quizás me la robe xD
Aunque quizás con un efecto on.mouse.over quedaria mejor
