Thanks for your response, sorry I didn't see it sooner.
I'm in the process of combining URL's/websites into one place and want to use my Squarespace site for many different things. Here's an example: There are times when I might want to share listings such as boats or cars without opening up my whole website to a buyer. This leads me to an interesting observation, thanks for that, Maybe I'm envisioning a website that is more personal than necessary, past my comfort zone. My website is not intended to be commercial, I've been thinking of it as a universal place to put things, like images, videos, writings etc. but I'm concluding that I need separate, independent places to put different things. I think Google docs will be useful, I'm finding that I can create and link to the docs when I want to share things but not put my website out there with it. Thanks for your question, it helped.
