If you would like to have this appear on your home page you can "Turn it on" under Settings > Website > Appearance > Theme. By default, we usually leave it off because we use the sidebar block to have the About the journal text.
This is an example journal we use for training. It has various author, reviewer, editor accounts all set up to send emails to email@example.com.
