I've got custom content-type. On the main page I set teaser display of contents and I decided to show off only several fields there. Next to each content I can notice text "Read more". After entering it, I am redirected to full display of contents (There are show off all fields).
Action, described above can be done by everyone. But, I'd like to allow it only logged in users. How can I disabled it for users who aren't logged in.
