Creates a new site where all the most recent posts/pages/etc on a WordPress network may be collected (much like http://wordpress.com/tags/).
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.
Based on and forked from <a href="https://wordpress.org/plugins/wordpress-mu-sitewide-tags/" rel="ugc">WordPress MU Sitewide Tags Pages</a> plugin by Donncha O Caoimh.
WPCLI is supported: 
 wp multisite_aggregate –help.
