Broadcast allows content to be quickly and easily broadcasted to one or more blogs in the network. If you choose to link the posts together, updating the source will automatically update all of the broadcasted child posts.
Broadcast will copy and sync the content, custom fields, taxonomies, featured images, attachments, galleries, etc. The base version, available from the WordPress plugin repository, can handle most situations, but if you need more functionality there also exists a premium pack that consists of over 30 plugins that increase productivity and compatibility with other plugins.
For example, the pack contains an Advanced Custom Fields compatibility plugin that allows for correct handling of ACF fields. Calendar plugins, a queue to work around the PHP time limit, custom field attachments handle images in custom fields, WooCommerce product broadcasting and stock syncing, etc.
