Okay, if you run a blog that spans across many different pages, there is a simple but affective way to organize that page. First off, you can create your own site map page template if you want using this tutorial, then put the following code in there to produce all of your categories and sub-categories in an orderly and appealing way.
<ul>
<?php wp_list_pages(‘exclude=12&title_li=’ ); ?>
</ul>
You can see an example of what this will output here.
