Mine is simple enough, it grabs the author name, looks for an include so you can have a different author bio layout, pictures, fb/twitter links whatever on that. And the rest just spits out the posts by that author.
Code:
get_header(); if(isset($_GET['author_name'])) :
$curauth = get_userdatabylogin($author_name);
else : $curauth = get_userdata(intval($author));
endif; ?>
<div class="post"><div id="post-archives">
<?php include('./'.$curauth->nickname.'.php');?>
<br />
<h2>Posts by <?php echo $curauth->nickname; ?>:</h2>
<ul>
<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link: <?php the_title(); ?>"><?php the_title(); ?></a>, <?php the_time('d M Y'); ?></li>
<?php endwhile; else: ?>
<p><?php _e('No posts by this author.'); ?></p>
<?php endif; ?>
</ul>
<?php get_footer();?>
