RSS Feeds...

I notice we have options to subscribe to RSS feeds on here per each board ID, but is there a single RSS feed that will let us subscribe to the whole board as a whole instead of individual sections?  

I have gone the route of RSS feed updates as they are more reliable than email updates and when I was checking subscriptions it said I could subscribe to each board that I wanted to get notification from if there's a new post, but never could find anything other than subscribing to an RSS feed. >.>
