Comments can be a great way to engage with your students. When you add comments to lessons they will appear at the bottom of each lesson. You can choose whether they are public or private comments. You can also select that you want to be able to 'moderate' comments before they are posted. Not only that but you can also engage with your students though comments. Posting replies to their comments.
