I tried playing around with those, but I could not get it to work. After
reading this:

I searched through the source code, it seems that every instance that I can
find of wp_print_styles() being called is somewhere on the admin pages. My
guess is that it is left to theme authors to impliment it in their themes
so, I decided to try what Callum suggested with this:


>    add_action('wp_head', 'wp_print_styles');


embedded in the function. What I have now is the following:

 // Include a link to the current templates tweaks.css if it exists...
function krusty_plugstyles(){
    if (file_exists (get_template_directory()) . '/tweaks.css'){
        // register and enqueue our css for later addition into the head of
the page
        wp_register_style('krusted-plugstyles', get_bloginfo('template_url')
. '/tweaks.css', array(), '', 'screen');
        wp_enqueue_style('krusted-plugstyles');

        // since wp_print_styles() doesn't seem to run by default
        // we add a call to it with the wp_head action hook
        add_action('wp_head', 'wp_print_styles', '100');
    }
}

// add an action to call our function when wordpress starts loading a page
add_action('init', 'krusty_plugstyles');

This seems to be working, but now I'm left wondering if I should use a
conditional on it, maybe something like:

if ( !did_action( 'wp_print_styles'  )
     add_action ( 'wp_head, 'wp_print_styles', '100' );

or would that even be worth it?

Thanks for the help folks, I do appreciate it alot! :)
