Broadcast MU Wordpress Plugin - Rating, Reviews, Demo & Download
Plugin Description
Broadcast MU is a plugin for WordPress which allows you to broadcast a post to one or more other blogs on the same installation of WordPress by simply checking the box next to those you wish to send it to.
You can enable this plugin on individual blogs or site wide.
This plugin is for WordPress Multisite installations only because regular WordPress only supports having one blog anyway.
