In a multisite environment, enables syncing or crossposting of posts, pages, or custom post types from any blog to any other blogs. 
The crossposted articles have exactly the same properties as the original except for the permalink 
which links back to the original.
The initial idea and some of the functionality is heavily borrowed from 
Code For The People’s Aggregator plugin https://github.com/cftp/aggregator/. Unfortunately, that hasn’t been updated 
in years, it’s vastly too complicated, the admin side of things is very clunky and it’s a bit slow. This plugin uses 
some of its methods as a base but has a much more streamlined admin process. We have maintained the same post meta 
field names so this plugin should be 100% backwards compatible.
