Re posting to another blog

Hi All.

I am trying to create a news network that consists of many seperate domains (Not multisite) which pick up their regionalised news posts from a central (parent) site.

(I guess this would be similar to a re-tweet but automated)

I was just wondering if any of you excellent and most helpful support peeps could offer your thought for the best way to achieve this.

I have been looking at rss feeds as it needs to be fully automated - ie post to the parent domain blog which then feeds to the child domain.

I wondered if there is another/better way to do this and if any of you could kindly offer up some suggestions.

Stef.

PS. Loving your plugins !
