						<?php if (have_posts()) : ?>

						<?php while (have_posts()) : the_post(); ?>

						<div class="entry">
							<?php the_content('Read the rest of this entry &raquo;'); ?>
						</div>

						<div id="contentHeader">
								<h1><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h1>
						</div>

						<?php the_content('Read More'); ?>

						<!--<span class="readMore">Continue Reading</span>-->

						<div id="contentFooter">
								<p>Published <?php the_time('M d, Y') ?> - <?php comments_popup_link('No Comments', '1 Comment so far', '% Comments and counting'); ?> </p>
						</div>
						<?php endwhile; ?>

						<?php else : ?>

						<h2 class="center">Not Found</h2>
						<p class="center">Sorry, but you are looking for something that isn't here.</p>
						<?php include (TEMPLATEPATH . "/searchform.php"); ?>
