It's easy to join from your Google+ account. From your own home page, type the message under "Share What's New" and send it to Juliette Wade. She'll send you an invitation (and will post the URL once the hangout has begun).
If you don't have a Google+ account, you'll be able to view the hangout and read a summary at a later time. I'll post links to that.
Hope to see many of you there!
