Multisite, also known as a WordPress network, allows for multiple sites to run under one WordPress installation. Plugins are available to add functionality like pulling posts across sites, mapping custom domains to individual sites, controlling plugin and theme usage, and managing users across the network. The document recommends several plugins for multisite networks that add features like broadcasting posts to multiple sites, setting defaults for new sites, customizing CSS per site, and providing statistics on plugin and theme usage.
