MU Post to Multiple Blogs

Creates a metabox on post edit pages, which allows you to select other blogs to post to within a WordPress multisite.

• Must be logged in as an network admin to see the box.

For performance reasons the number of posts is limited to a user configurable amount, and the blog itself can be made indexable by search engines or not.

This plugin was based on another WP plugin: https://wordpress.org/plugins/wordpress-mu-sitewide-tags/

Install

1. Install in your plugins directory in the usual way and network activate the plugin. There is no need to put it in mu-plugins.
2. Login as a site administrator and go to Super Admin->Sitewide Tags.
   1. « Max posts » defaults to 5000. Older posts will be deleted if this threshold is broken.
   2. Check « Include Pages » to include both posts and pages, handy for making a sitewide search.
   3. « Privacy » defaults to public, pages can be indexed by search engines.
   4. When « Privacy » is not public, check « Non-Public Blogs » to include blogs not indexed by search engines.
   5. Add « Post Meta » custom fields to be copied with posts/pages.
