author.php including comments template as pinboard?

Hey guys,
i am trying to include the simple comments_template() tag into my author.php for to make it possible to comment on this author’s profile page as if this was a pinboard. is this simply not possible or am i too stupid? 😉

i’m using wordpress 2.3.3 and a sexy k2 theme. which code do i have to embed into the author.php for showing a comment-text-field and so on?

this is what my code looks like till now:

<?php get_header(); ?>

<div class="content">

<div id="primary">
<div id="notices"></div>

<div id="current-content" class="hfeed">

<?php
if(isset($_GET['author_name'])) :
$curauth = get_userdatabylogin($author_name); // NOTE: 2.0 bug requires get_userdatabylogin(get_the_author_login());
else :
$curauth = get_userdata(intval($author));
endif;
?>

<p><h3 class="entry-title">Profil: <?php echo $curauth->nickname; ?></h3></p>

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<!-- <span class="avatar"><?php if(function_exists(cmd_show_avatar)) cmd_show_avatar(avatar); ?></span> -->

<?php endwhile; else: ?>
<p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
<?php endif; ?>

</div> <!-- #current-content -->

<div id="dynamic-content"></div>
</div> <!-- #primary -->

<?php get_sidebar(); ?>

</div> <!-- .content -->

<?php get_footer(); ?>

please tell me that it’s possible and i’m just too stupid!! HELP!!
