Multi-Site: How can I move a blog post from one site to another?


I have a web community which is harming itself in terms of Google search ranking.

It is a site for writers and as such, it has articles about the craft of writing, etc, but then it also has book reviews, short stories, poetry, you name it and ... I'm fed up - they don't listen.

Thanks in advance.
