This plugin is for site owners who publish content and want to automatically notify central hubs when new posts are available. It implements the PubSubHubbub (PuSH) protocol, which is a common standard for real-time content syndication.

• Automatic Hub Notification: When you publish new content, the plugin automatically sends a ping (a "PuSH") to a specified hub server. This eliminates the need for manual pinging or waiting for hubs to discover your updates through slower polling methods.
• Microformat-Based URL Detection: The tool identifies the correct URL to notify by reading the site_url from your site's HTML markup when it is formatted with the h-feed or similar microformats. This ensures the notification points to your main content feed.
• Protocol Compliance: It adheres to the PubSubHubbub core specification, ensuring reliable communication with compatible hubs and subscribers in the federated content ecosystem.
• Dependency on Webmention Plugin: This tool requires the separate Webmention plugin to be installed and active on your site, as it builds upon that foundation for discovery and communication functions.
