Thank you.
I had already found that it had to work that way to make the menu tems.
But now I have a user who can also create newsletters. That user is a member of a special user group.
I also linked the access for that menu item to that group.
However, the user does not see any lists or users when he opens such a menu item.
What else do I need to do to make sure that user sees lists or subscribers on those menu items.
