This is an existing website that has many daily users. I was hired to take over the website and make some design changes, copy updates, photo edits and changes to navigation and branding. I need to be able to work on these changes in an environment that will allow my client time to review, ask for changes and proofread. And also allow an adequate amount of time for testing. In other words have a working version that can be shared with my client before it is "Published". The general public (our customers) still need to be able to access the site so it cannot be password protected. Every site I've worked on since the mid 90's has allowed me to do this. If SquareSpace does not have this capability, I just need to know so I can recommend using a different platform.
