I researched at length my WordPress theme The Morning After (which it was beginning to feel like) and determined it’s fancy-schmancy!
In short, when I prepare a new post, I may choose to stick the previous (or any other post) to the front page of the blog!
Having found this control, I have done so, and now Guffaw in AZ really looks as a blog should!
Thanks kind readers for all your help and advice. I’m still in the learning curve!
