Comments Styling

I am using NeoSapien. It seemed to be -slightly- outdated and I’ve tweaked it a bit. It didn’t have the $oddcomment so I added what I found.. resulting in this

<?php foreach ($comments as $comment) : ?>

<li class="<?php echo $oddcomment; ?> " id="comment-<?php comment_ID() ?>">
 <?php
   echo get_avatar( get_comment_author_email(), $size = '50', $default = 'http://www.ofsexandlove.com/wp/wp-content/themes/ofsexandlove/images/avatar.jpg' );
   ?>

	<cite><?php comment_type(__('Comment'), __('Trackback'), __('Pingback')); ?> <?php _e('by'); ?> <?php comment_author_link() ?> on <?php comment_date() ?> <a href="#comment-<?php comment_ID() ?>"><?php comment_time() ?></a></cite>
	<?php comment_text() ?>
	</li>
<?php /* Changes every other comment to a different class */
    if("altcomment" == $oddcomment) {$oddcomment="";}
    else { $oddcomment="altcomment"; }
?>
<?php endforeach; ?>
