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.

This is very simple plugin to provides information about the last login activity on you blog account, If you’re concerned about unauthorized access to your blog account, you’ll be able to use this information to find out if and when someone gained access. 
The IP address is also useful. If you always or most often sign in to your blog account using a single computer, your IP address should be the same, or start with the same two sets of numbers (for example, 125.16.xx.xx). If you’re seeing an IP address that differs greatly from your usual IP address, it could either mean that you’ve recently accessed your account from a different location, or that someone has accessed your blog.

WordPress Last Login

This feature provides information about the last login activity on your blog account and any concurrent activity.
