A previous topic on this same subject is no longer visible, so I’ll ask on my own behalf.
Several places in this book have text that appear to be web links, but as I’m reading the PDF version in macOS Preview, they do not respond to clicks. For example, page 57 near the bottom are apparent links “developer documentation” and “free tutorial”, both inert.
Is there some place in the RW web site where these links can be accessed?
