In my skin I see the following code:

<?php posts_nav_link(); ?>
	<?php 
		// previous_post( '<p class="center">%</p>' );
		// next_post( '<p class="center">%</p>' );
	?>

It's placed right after the "END OF POSTS" and right before the "START OF INCLUDES FOR LAST COMMENTS, STATS, ARCHIVE DIRECTORY, PROFILE, FLIGHT LOG.

Hope that helps.

many thanks for your help. you were right, the code was missing.

but so too was a critical setting in the back office -- for some reason, under the 'Settings' tab, i had the 'Display mode' option set to 'posts' instead of 'posts paged.'

so no matter how much i fiddled with the missing code in the skin, i couldn't get it to work. it was driving me crazy. luckily i have a copy of the site running locally with the right settings - otherwise i would NEVER have worked it out.

thanks again.
