Can I completely disable sending this annoucement?

Can I competely disable sending this annoucement? This confirmation page appears in browser when the subscriber confirmed (by clicking link) e-mail send to him.

I asked earlier how can I edit content of it but haven’t got solution.

@maciej67 You would need to change the phplist code in file lists/index.php to alter that.

But your screenshot appears to be showing something unusual. If someone has confirmed their subscription then they would have used a subscribe page with a public list to do that. So “None of them” should not occur. Instead the name of the list should be displayed.

Maybe you changed the list visibility after the original subscription.
