Overview
The addition of Recent Posts to the side bar gives you a list of your recent posts based on selectable parameters from the "Options" admin page in the same style as the rest of the sidebar. You can get this to appear in other places but may take more expertise.
Instructions
Download, unzip and upload to the plugins folder of your server then activate it
Go to your "sidebar.php" file found in the theme folder of the theme you are using scroll down this until you get to something you recognise for example:
<h3>Pages</h3>
<ul>
<?php wp_list_pages('title_li='); ?>
</ul>
then add in above it:
<li><?php the_recent_posts(); ?></li>
this will then appear above your pages listing. You can of course choose where in the sidebar it should appear.
Go to your site to test!
