Buddypress – Send New User Activation Link to Admin [closed]

Reading the code I would try something like this:

add_filter( 
    'bp_core_signup_send_validation_email_to', 
    'wpse_60858_catch_user_signup_mail' 
);

function wpse_60858_catch_user_signup_mail()
{
    // make sure to use a valid email. test it with different addresses
    return get_site_option( 'admin_email', '[email protected]' );
}

This changes the $to part only.
