The "Sage is starting" screen seems to have two issues:
(1) If I point my browser to localhost:8080, which is what the "Sage is starting" screen tells me the Jupyter interface should go to, I get a "connection was refused" error. I am guessing that's just a mistaken link. But what port should I be going to? 8888?
(2) It says if problems continue, to email support and gives a link of mailto:sage-support@groups.google.com. Following that link and sending an email gives an autoresponse of "Delivery Status Notification (Failure) We're writing to let you know that the group you tried to contact (sage-support) may not exist, or you may not have permission to post messages to the group." It seems to me that if people are required to join a google group in order to get support, that should be part of the instructions rather than telling users to directly email the group.
