Erica, Rick actually did the mobile menu thing and he did it from the Mobile Menu Options, on the left about five items up from the bottom. This link may or may not take you there – https://rrvarc.org/wp-admin/admin.php?page=mobile-menu-options&tab=general-options.
I still want to see if we can come up with a page that is only visible to admins and which is not reflected on home page whenever you can look into that. Much thanks! – Phillip
