I went through the tutorials but couldn't find anything on frontend users. Hope I didn't miss that in the docs.
I simply want to show certain pages in the frontend only to users which are registered on the site. However these users should not have any access to the backend but I would need to set access in the backend of course.
It would work the same way. If silverstripe gets a request of a page that requires login it redirects to the login screen. The user logs in and is then directed to the page he or she tried to access. The problem seems to be to get links for these pages out in the menu. I don't know how to do that, sorry.
