Hi Adrian,
Thanks for your response.
There are two aspects to what I am doing:
(1) the information I'm presenting is confidential and I can't make it available to the public. I think if I was to create simple web applications (as per your examples) I would need to Share it as public?
(2) if I make it private, then I need to provide login credentials. I'm currently the only named user/member as well as the administrator, so users would be using my credentials to login to the site but this will also give them administrator privileges. For example, if they truncated the URL I sent them to the "root path" they would be able to access the My Content and My Organization sections of the subscription - where they could easily make changes.
I'm thinking that I may need to purchase additional members/named users, set up roles and groups with restricted privileges and then provide relevant login credentials?
