Looks like the ability to get alerts via an RSS feed has gone.. I've gotten less and less email alerts over time I honestly thought this would be something Google had on the deadpool list
It's there. When you edit and show options, you can deliver to email or RSS.
It's been gone for a while. But it's honestly to be expected that Google pulls only dickmoves regarding RSS, since RSS is actually counterproductive when it comes to showing ads.
