Hello, If a login is not required, anonymous users can go to the site to view the pictures and other postings. If a login is required, you have to add each person as a member or set a guest password. If someone enters the guest password, they are only given permission to add comments to pictures and post discussions. You can set a guest password by going to the member area and clicking "Security". Click "General settings" and enter a guest password. Everyone that is not a member has to use this guest password.
