Bingo! Thanks.

Thank you.  (not sure why i didn’t think of that)  I used a simple conditional statement and it worked like a charm.

if ( is_user_logged_in() ) {
    wp_nav_menu(array('theme_location' => 'main', 'menu_id' => 'menu'));
} else {
    wp_nav_menu(array('theme_location' => 'visitor', 'menu_id' => 'menu'));
};

I did have another question. I included the [wpuf_dashboard] shortcode which displays the list of posts. When I click “edit” on one of them it takes me to the form but none of the existing data is there. Is this correct?
