Broadcasted posts can be linked to their parents: updated parent posts also update the child posts. Child post permalinks can be overriden with a link to the parent post.
Last used settings are remembered between uses. Broadcasted categories keep their parents, as long as the parents already exist on the child blog of if the parent is broadcasted and created simultaneously as the child category.
Has options for whitelisting (required blogs), blacklisting, user role access granularity, category and/or tag posting (if the blogs have the same category slugs) and category/tag creation (automatically, per user role) and an uninstall to completely remove itself. No traces of the plugin are left (assuming the created tables are successfully removed).
Available in English, Swedish and Dutch.
