Thanks so much for replying! I am president of the Coding Club in my high school, and a lot of the rails teaching that I'm doing is based off of what I learned in your book. The school doesn't allow installing software on the computers, so using a Cloud IDE will be perfect for us. Thank you so much for writing such a great tutorial!
You could make a start page. Users can add calendar info, schedules, pictures of family/friends, and anything else that they want to see when they open up their browsers.
Of course this would also be useful for yourself if it's more of a personal project.
