I know your brain is full because you have a PHD. We might have to fly Harrison out to the chicken farm to explain how to post to a blog.
Once you get to the blog, you have to Sign In. You can only sign in to the blog with the email address that you registered on Google with. It's true. Ask Lara.
Once you are signed in, click on New Post.
You can write stuff. You know, writing. I think you might be able to do that.
The posting screen has an icon that looks like a little picture. If you click on that, you will get a pop up menu that allows you to select photos from your computer. Click on Save.
When you are all finished, click the orange Publish Post button on the posting page, and Bob's your uncle, you can mock the rest of us.
