This plugin works on multisite WordPress installs only.
Use this plugin when you need to add a page on multiple website installs of a WordPress multisite without doing this manually.
You have the following options for adding the page: 
* the list of sites you want to add the page to 
* page title 
* page slug 
* page content

In case your page already exists (has the same slug) on one of the websites, the page title and page content will be updated.
