Looks good, but you don’t need to copy the template. Just add this function in your child theme’s functions.php file (or wherever you put the other code):

function my_theme_add_activity_tab() {

if ( !is_user_logged_in() )

return false;

?>

<li id="activity-myclass">

<a href="<?php echo site_url( BP_ACTIVITY_SLUG . '/#myclass/' ) ?>" title="<?php _e( 'Activity for my Class Year.', 'buddypress' ) ?>">

<?php printf( __( 'My Class', 'buddypress' ) ) ?>

</a>

</li>

<?php

}

add_action( 'bp_activity_type_tabs', 'my_theme_add_activity_tab' );
