My client would like to create a Ghost site that would for now be solely internal, aka accessible only to company employees. There is consideration for potentially allowing the public to view select content in the future. My understanding is that there is a system for dividing site visitors into paying/non-paying users, aka members vs. non-members - can this system be converted into internal vs. external site viewers?
Additionally, for analytics purposes, how would visitors to the site be tracked? Employees at the client’s company would share the same IP address, so there is a need to track individual visitors by something else such as by a company email.
