Within my SharePoint 2013 site, I have a blog subsite, within my main site I see a Blog Notifications web part that I can add to my home page. The description for that web part is {Provides quick links to register for blog posts notifications using Alerts or RSS feed}, I created an RSS feed from my blog site, however, how can I show it within the Blog Notification web part? When I go to edit web part there is nothing there to configure it to read something.
I know how to read the blogs from an CQWP, however, I was hoping to use the blog notifications web part.
can I even use it or is a useless web part?
