Alright! I did it. And if anybody wants to know, here’s how:

This code in the stylesheet

ul.taglista { list-style: none; margin: 0; padding: 0; }

ul.taglista li { display: inline; }

ul.taglista li:after { content: ","; }

ul.taglista li:last-child:after { content: ""; }

And this in topic-tags.php

<?php if ( $user_tags ) : ?>

<?php _e('Your tags:'); ?>

<ul class="taglista">

<?php foreach ( $user_tags as $tag ) : ?>

<li id="tag-<?php echo $tag->tag_id; ?>_<?php echo $tag->user_id; ?>"><a href="<?php tag_link(); ?>" rel="tag"><?php tag_name(); ?></a> <?php tag_remove_link(); ?></li>

<?php endforeach; ?>

</ul>

<?php endif; ?>

It won’t work in IE, but that’s fine with me. Thanks for the help!
