I want to create a login page but only for specific pages.  So a visiter can visit my site but only need to register when submitting information.  One use case: I have a page where drivers will be coming to the site and I want them to register and fill out an application.  This way later on they can login to the site and modify their application and track it.   How do I make so login, or creating a log in, only apply to specific pages and not the whole site.   Thanks.
