If a Ning Network is public, you can subscribe to its videos using RSS. Click on the Videos tab and scroll to the bottom of the page. Click the RSS link toward the bottom of the page to copy the feed.
Next, go to your external website or feedreader of choice. A good place to start is iGoogle, which is easy to configure and comes with a bunch of default feeds that will give you an idea of what you can use RSS for. To add a feed to your iGoogle, click the “Add stuff” link at the top right of the page. Next, at the bottom of the left column, click the “Add feed or gadget” next to the RSS icon.
Paste in the URL of the RSS feed you copied from your social network and click the “Add” button. Once your feed has successfully been added, click the “Back to iGoogle home” link at the top left of the page. Your new feed will appear in the top left corner of the page.
