Would you like to have global (i.e. site wide) RSS feeds for every tag and category on your WordPress MU site?

Cool, well this plugin does exactly that for you :)

Just make sure you have our post indexer plugin installed and then drop this plugin into /wp-content/.

Now, if someone on blog1.yourdomain.com writes a post and tags or categorizes it 'politics' and someone on blog45.yourdomain.com also write a posts and tag or categorizes it as 'politics' - now both of their posts will appear in http://yourdomain.com/wp-content/tag-feed.php?tag=politics

For example:

The domain wordpressmu.org global tag feed for the tag term WPMU is located at http://wordpressmu.org/wp-content/tag-feed.php?tag=WPMU

Neat huh :)

And you can do that for any tag or category on the entire site.

Simply edit this formula to suit your requirements:

http://yourdomain.tld/wp-content/tag-feed.php?tag=TAG

Here's global tag feeds for WPMU, Twitter, Chocolate and PLN being used on the WPMU Dixi theme
