That did it … thanks!

(Note to anyone trying to duplicate: Looks like to include a specific category rather than exclude, you remove the minus sign.)

I added the code between

<?php
	if(!stristr($_SERVER['REQUEST_URI'],'/page/')) {
		if(get_option('uwc_latest_story') == "on") { echo '<h5>Latest Story</h5>'; }

and

if(get_option('uwc_post_layout') == 1) { include (TEMPLATEPATH.'/layout/option1.php'); }
		if(get_option('uwc_post_layout') == 2) { include (TEMPLATEPATH.'/layout/option2.php'); }
		if(get_option('uwc_post_layout') == 3) { include (TEMPLATEPATH.'/layout/option3.php'); }
		if(get_option('uwc_post_layout') == 4) { include (TEMPLATEPATH.'/layout/option4.php'); }
	} else {
		include (TEMPLATEPATH.'/layout/default.php');
	}
    ?>

… of course, that might be theme-specific. (I’m using Magazine Basic.)

(Please disregard the question about My Category Order — the Category Order plugin seems to work.)
