If you want to communicate with readers on a blog, the best way to achieve this is by setting up comments. If you're happy to deal with spam and the occasional troll, then comments are great for communicating with readers and fostering a community.

The functionality has changed a lot in Drupal 8. In Drupal 7, the comments system was fairly rigid. You could only use them on content types and only have a single comment type. If you needed to support multiple comment types like review or feedback, you were out of luck.

In Drupal 8, the comments system has been rebuilt. They can be attached to any entity type by adding a "Comments" field. You can also now have different comment types. This allows you to do all sorts of things like having public and private comments on a single content type.

In the last tutorial, we created a Blog content type and added fields to it. Let's continue working on it by adding support for comments. We'll configure the user permissions so that comments can be submitted anonymously, but will need to be approved before they're published.
