WordPress MU

Hi,
Is this possible and if yes, how do I achieve it?

I have the domain Soccerstar.org. On that I would like to publish the latest posts from all the sub-blogs, blog1.soccerstar.org etc.

I would also like to re-publish all posts with a specific tag to a sub-blogs. For example:

I have different player-blogs, lionelmessi.soccerstar.org etc. I also have team-blogs, barcelona.soccerstar.org. Is it possible to have all posts from lionelmessi being re-published at barcelona.soccerstar.org?

Kind regards,
Daniel Bergstrom

You may want to search the forums for 'cross posting' as this has been discussed multiple times. I believe we even had a thread on it 2 days ago.
