In this session we discussed how our automated website platform works.
We learned that it allows us to create and maintain an unlimited number of WordPress sites (or as many as our hardware supports) on a single network. All websites on the network share a single filesystem which simplifies theme/plugin updates and other maintenance.
All sites also share a set of core tables, but have their own post, post meta, etc. tables to have their own content, settings, etc.
