Disable New Page Creation

Is there a way I can disable the creation of new pages, but at the same time have them edit their own existing pages? I’m trying to create an Intranet site with WordPress, and have the role-manager plugin installed. I can have it as to where the user can only edit their pages, but will still see the “Add New” link under pages.

Even if I could just hide all the links to add a new page, that would be great. Thanks.
