Start by enabling comments for your publication:
- Log in to your account and navigate to Dashboard > Settings.
- Scroll down to "Publication details" and click "Enable community features".
After you've enabled comments, you can choose whether to allow comments on a per-post basis. From the post editor, click Settings:
If you choose "everyone", readers will still be asked to provide their name and email before they can comment on your posts.
If you have a paid publication, you can also choose whether to only allow paying subscribers to comment.
After you've published your post, you can go back and enable or disable comments anytime.
