Delete an Activity Stream?

[Underwatr]

I was playing around and created an Activity Stream to show me all content from a particular user. It now appears on My Activity Streams below the default ones (good to know, I'll use that a lot later). But how do I delete the Activity Stream that I just created? It wasn't obvious before I've had my coffee. 🙂

When you're looking at the stream, just to the right of the title are three icons.  The second one (in red) removes the stream.

Success! Thanks.
