On a single post (single.php), I'd like to show what's below the <--More--> tag to registered users only, and not to unregistered users. I've been searching for way too long and I can't find a solution.
All of the codex entries say the_excerpt isn't available on single posts, but it seems like there's got to be a way around that. I have full access to customize the template's php as much as needed.
Or a different approach with the_content?
Is there a genius out there?
