I have a friend that was unaware that she was a "no-reply" blogger and didn't know how to change it. I found a tutorial using the old view, but I didn't find one for the "new" view so I did screen shots and told her how to do it. I thought... since I already did that much I may as well share it with y'all.
1. From your home page; click “Design” in the top right hand corner:
2. From this new window click on the drop down arrow next to your name:
3. When the dropdown window opens click on “Blogger profile”
Clicking “Blogger Profile” pops open a new window.
4. Click on “Edit Profile”
5. Make sure “Show my email address” is checked
6. Scroll down to the bottom left and click “Save Profile”
