I did not get it done, for some reason. I used an approved browser (Firefox for Mac); I got my account set up and the blog verified. I took the screen shots required and made them GIF files, as told to do. But when I clicked to upload the pictures, nothing happened.
Maybe it's because I'm using an Apple computer. No biggie, anyhow, but I wanted to pass the word along so others could do this if they so desire.
