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.

Helper functions to make developing solutions with WordPress MU or BuddyPress easier. Right now there is a function to return all posts from all blogs, and one to return all comments on all blogs. The code is well commented with phpdoc blocks, so read the source for more info. This plugin is for developers and will do nothing on its own (except provide functions to developers that don’t exist in the core API)
