How do I use subscriptions?

Thought I'd dig this out of the Community 'Help' bit:

 

"Subscriptions let you get email updates whenever new content appears in an area of the community that you're interested in. You can subscribe to a board, a blog article, an idea exchange, or any other location in the Community. You can also subscribe to a specific post.

 

To subscribe a piece of content:

 

1. Go to the item you want to subscribe to.
2. To subscribe to a location, click (Location) Options > Subscribe.
   To subscribe to a specific post, go to the post and click (Post) Options > Subscribe

    

To view and manage your subscriptions:

 

1. Go to My Settings > Subscriptions & Notifications.
2. Click My Subscriptions to see a list of the items you've subscribed to.
   You can click a subscription to go to the item.
3. To delete a subscription, click the check box for the subscription and click Email Subscription Options > Delete Selected Subscriptions."
