We have recently built a wordpress real estate network for the group of offices under the Great Ocean Road Real Estate brand. They have a group website www.greatoceanroadrealestate.com.auand then 6 office websites. They wanted a solution which allowed them to post an article on the corporate website blog which also appeared on the other network websites.
We built a small Multiple Post plugin which allows blogs to be post on an unlimited number of worpdress blogs as long as they are situated on the same server. The post writes to the other blogs and inserts the exact same wordpress post with the same title and description as what is on the original post. It also creates identical tags and categories which were used on the original post.
What’s even better about the plugin is that if you update the post on the original blog it will filter through to the other blogs the post appears on.
Another awesome example of the robust nature of using WordPress CMS.
