Ideal for creating global RSS feeds across your network that anyone can subscribe to.

Global Tag Feed lets you cater RSS feed content to the needs of your users’. Give readers the ability to subscribe to content marked by a specific tag.

If posts are made, on two different sites on the same network, with matching tags or categorizes both posts will appear in the tags feed.

Here are some examples of how Global Tag Feed can enhance your network:

• Integrate with themes that pull RSS feeds onto its homepage
• Add it to a third-party RSS feed widget in the sidebar of your site
• Allow readers to subscribe to only the topics that interest them

Install Post Indexer by WPMU DEV and Global Tag Feed. Then upload the included tag-feed.php file to your wp-content folder and your new feed is created. See the new feed

http://yourdomain.com/wp-content/tag-feed.php?tag=tag_name

Important: the Post Indexer plugin must be installed and activated on your site before installing this plugin.

Once the Global Tag Feed plugin is installed, move the tag-feed.php file from your plugins folder to your wp-content folder.

Now network-activate the plugin. Your new feed will be created at:

http://yourdomain.com/wp-content/tag-feed.php?tag=tag_name.

You can check that it is working correctly by:

Step 1: Publishing a few new posts with the category or tag you want to create a feed.

Step 2: Checking the feed by going to the tag feed URL in your web browser.

Please note:

• It can take some time for the first few posts to appear in the tag feed URL in your web browser and normally takes longer to feed through to RSS readers like Google Reader.
• So if your posts don’t appear in the tag feed when first published check again in an hour.
• The tag feed displays feed from public sites only. Posts from privates sites aren’t displayed.
