Here's how to get rid of the "Comments" function all together.. =)
First, in pollbooth.php around line 164 change it to look like this:
//$post_details = _COMMENTS_BY . $comment_name . '['. $comments['host_name'] . ']' . _COMMENTS_ON . $comments['date'];
$post_details = "";
Then, in pollbooth.php around 193 change it to look like this:
<tr><td colspan="2" align="center" class="main">[ <a href="<?php echo tep_href_link('pollbooth.php','pollid='.$pollid.'&op=vote','NONSSL')?>"><? echo _VOTING?></a> | <a href="<? echo tep_href_link('pollbooth.php','op=list','NONSSL')?>"><?echo _OTHERPOLLS?></a> ]</td></tr>
I think that's it =)
