If your feed is PuSH (pubsubhubbub) enabled, dlvr.it automatically subscribes to PuSH updates from your hub. This means dlvr.it will get your feed updates immediately when your feed updates.
However, there are some cases where you may not want dlvr.it to receive PuSH updates.
To stop dlvr.it from receiving PuSH updates for your feed:
1) Log into your dlvr.it acocunt.
2) Edit the feed you wish turn off PuSH updates for (click on the feed, click the edit/pencil icon)
3) Go to the Feed Update Tab
4) Toggle the "Subscribe to PuSH updates" to the "off" position:
After you make this change, dlvr.it will no longer subscribe to your feed's PuSH hub -- and we'll continue to check your feed by polling your feed url according to your Feed Update schedule.
