Re: remove ’register link’ from admin bar
`function cc_admin_bar_links() {
global $wp_admin_bar;
//BE GONE DEMON!
$wp_admin_bar->remove_menu(‘bp-register’);
//AbraCaDabra! Once i wave my wand, you will become an Elephant!
$wp_admin_bar->add_menu( array(
‘id’ => ‘bp-login’,
‘title’ => __( ‘Log in and register’, ‘buddypress’ ),
‘href’ => wp_login_url()
) );
}
//Wave Wand.
add_action( ‘wp_before_admin_bar_render’, ‘cc_admin_bar_links’ );`
SORRY! Don’t mind my lame humor within comments. Just remove them 
If this doesn’t work, you will need to contact wpmudev as they are probably doing something really weird
