Okay, running into a brick wall. :-b
It looks like what I need to do is have TWO menus defined. I've created MEMBERSHIP and LOGIN as my two menus.
Only one can be the Primary menu for the Twenty-ten theme.
So what I guess I need to do is to programically change the Primary Menu for when LOGGED IN or LOGGED OUT.
Can I do this? So far I'm not sure.
I figure this all have to be done BEFORE the code in header.php is reached...
<?php wp_nav_menu( array( 'container_class' => 'menu-header', 'theme_location' => 'primary' ) ); ?>)
...
Anyone? Anyone?
