@rkread - take gene's code and add your link in somewhere. i am not sure which div you'd like it to appear in, but let's take for example that you'd like it to appear in a div before the #access div
function remove_thematic_access() {
remove_action('thematic_header','thematic_access',9);
}
add_action('init','remove_thematic_access');
function my_category_access() { ?>
<div id="about_link">
<a href="#">About Link</a>
</div>
<div id="access">
<div class="skip-link"><a href="#content" title="<?php _e('Skip navigation to the content', 'thematic'); ?>"><?php _e('Skip to content', 'thematic'); ?></a></div>
<div class="menu">
<ul class="sf-menu">
<?php wp_list_categories('title_li=') ?>
</ul>
</div><!-- .menu -->
</div><!-- #access -->
<?php }
add_action('thematic_header','my_category_access',9);
or you could also add it to one of the empty hooks in the thematic_header 2,4,6,8 are all empty. see: http://bluemandala.com/thematic/thematic-structure.html to help you figure out which one you'd like to add it to:
function about_link() { ?>
<div id="about_link">
<a href="#">About Link</a>
</div>
<?php }
add_action('thematic_header','my_category_access',2);
and where i've written 2, place the hook you've chosen from the diagram.
@john - the 2 pieces of code are not meant to BOTH be placed in your functions.php. does that help?
