Here we go.

Welcome to MOLTO everybody!

This node you are reading is created as a Story node but that is not all: it is visible only to authenticated users. If you do not login - you do not see it. This is achieved under the tab "Access control", in edit mode. On the access control page you can disable view by anonymous on content of type events, publications, and on stories. For instance, I just used it to upload official project documents and I set them to be visible only to authenticated members.

Enjoy.
