deriving a separate subset website from my existing one
I am considering creating a new SM site that has only a subset of the material on my current site, which is remarkableimagery.net. My idea is for the new site to initially inherit the infrastructure of my current site (including its modified theme and existing HTML and CSS augmentations). Then, I would populate the new site with a handful of galleries, some which are already on my current site, updated About page, etc. My current site would continue to function with its current content. The new site would operate on a new custom domain.
I'm hoping that getting such a derived site operational will be straightforward and quick. Once it is operational, I may further customize it, diverting from my current site, but I'd like to have it operational quickly.
