By default, Blogger puts a "Navbar" at the top of your blog. This is great if you want to find other blogs. There is even a "Next blog" link, which will take you to a random blog. Wait a minute! You may not want your students or their families to click on this link and be unpleasantly surprised. Here is how to remove the Navbar from your blog.
1. Go the layout settings of your blog
2. Click "Edit" on the Navbar box
3. Scroll down and select "Off"
If you forget how to get to your blog settings, just go to blogger.com while you're signed in.
