A typical site would be a few pages that everyone has access to, but there would also be a few pages that could
only be accessed by people who passed a login page
I know it's not difficult to make a login page e.g. with WordPress, but the difficult part is making sure that some
pages can only be accessed by people who successfully passed the login page.
Anybody with experience in setting up such a site with WordPress ( I suspect I need to install a plugin for that ? )
