Uh a quick modification to your hack that makes it look more slimline.
// Change the Whole of Template: forumhome_stats_poster
// To the following.
PHP Code:
<tr>
<td width="100%" class="smallfont"><strong><a href="member.php?u=$getstats_poster[userid]">$getstats_poster[username]</a></strong></td>
<td class="smallfont" align="right"><b>$getstats_poster[posts]</b></td>
</tr>
