Welcome to the Learning Rails forum. I'm hoping that this will provide a home for discussion about the book, as well as an easy place to keep track of the latest news about it.
To get started, I'd like to suggest visiting the Excursions On Rails site, which links to lots of information about and from the book. A key feature there is the screencasts I'm posting to help people find their way through the book and get started with Rails.
I'll have more announcements as things come up, but certainly, please feel welcome to ask questions about the book!
