Broadcast’s most important feature, and its main advantage over RSS syndication, is its ability to link posts to each other. When linking is enabled all posts are updated with the same data, without requiring the same, repetitive manual editing.
Broadcast uses a parent / child paradigm: when a post is broadcasted – and linked – it becomes a parent post to one or more child posts. Each parent can have one child post per blog.
If you broadcast a post without linking it will just create a duplicate post on each selected blog. If you republish the post without linking it will create another duplicate.
Posts can be unlinked from each other using the bulk actions in the post overview.
If your page is under another page, and you wish to keep the same hierarchy on the child blog, ensure that the parent page is broadcasted before broadcasting the current page. Broadcast will see that the parent page has a child page on the child blog and place the broadcasted page in its correct place.
If you notice that posts are only linked in one direction, for example a parent links to a child but the child doesn’t link back, it might be a good idea to run a broadcast data maintenance check. See the admin settings menu, maintenance tab. Don’t forget to backup your database in case something goes wrong.
The linking data is stored in a separate database table that ends with broadcast_broadcastdata.
