I probably won't read it either. It's just the nerd in me wanting to know why the second one was not set up to receive those docs. I suspect it's due to the auto-registration process attempting to create a second Kindle email address that was the same as the first, and failing. So instead it set it to "@Kindle.com", which is clearly wrong on many levels. I changed that to a real email address, but that wasn't enough to queue the documents.
Fascinating, I know!
