pages only for members

Hello Mina, For now I have only one question left. Now front page is almost finished (except a few minor things), I want to make the rest of pages. One ting is crucial. A n umber of these pages are only for members, like a members list. I know how to login and logout. That isn't the problem. Problem is: how can I give a menu item (or item on te pages list) the caracteristic of a closed page. In the former Wordpress version it was easy. Now I don't see a possibility. Can you tell me where to find this? Kind regards Hans Hagmeijer
