Once Twitter integration is enabled on your Ning Network and you are connected to Twitter, you can use Twitter to announce when you’ve added new content. When adding blog posts, forum discussions, groups, photos, videos or events, you’ll now see a check box to share your content on Twitter.
Once you add the new content, a tweet will be sent to Twitter that links to your new content. If you don’t want to share new content you’ve added, simply uncheck the box. Your Ning Network will remember your preference the next time you upload new content, so the box will either stay checked, or un-checked, depending on your last action.
