Yes, after looking at a Blogger tutorial, I created my first Tab at the top of the page. Curiously, it's not considered a post. I found this out when I opened the Dashboard, clicked Edit Posts and read that there were no posts. So I clicked on the Edit Pages link above - the one I'd clicked on to create the tab, which seems logical! - and four different Tabs entries (my 4 attempts) appeared. We can Edit, Delete or View. I deleted three of the entries.
