I want unregistered users to only be able to see my "welcome..." node. I set that node's permissions to "allow" for that user group, and on General Permissions for that user group i selected "not set" for View and View Mode. But, unregistered/unconfirmed users cannot see any nodes. How can I change this? I want them to see a "welcome" node with general info and instructions for how to subscribe to my forum.
