PuSHPress Plugin

This plugin adds WebSub/PubSubHubbub ( PuSH ) support to your WordPress powered site. The main difference between this plugin and others is that it includes the hub features of PuSH, built right in. This means the updates will be sent directly from WordPress to your PuSH subscribers.

Frequently Asked Question

How is this plugin different from other PubSubHubbub plugins?

Other plugins use 3rd party hubs to relay updates out to subscribers. This plugin has a built in hub, allowing WordPress to send out the updates directly.

Is there anything to configure?

No, once the plugin is activated it takes care of the rest.

1. Upload pushpress.zip to your plugins directory ( usally /wp-content/plugins/ )
2. Unzip the pushpress.zip file
3. Activate the plugin through the ‘Plugins’ menu in WordPress
