What is this? Go here, for an explanation.
We see this confusion, a couple times a week, in Blogger Help Forum: How Do I? . Where is the dashboard? In the Classic Blogger GUI, the display which contained the "Blog List" (at the top), and the "Reading List" (at the bottom) was labeled "Dashboard". Many people also called the "Settings" / "Template" screens for the various blogs, linked from the Blog List, the dashboard. The New Blogger GUI has no page with the label - and no links "To The Dashboard". The Navbar (another unlabeled feature) has two links - "Design" and "New Post" - which lead to different dashboard sections, when you are appropriately logged in to Blogger . And, the "B" logo at the far left of the navbar will, similarly, take you to the Blog List / Reading List.
