To enable Reactions, log in to your dashboard, go to Layout > Page Elements and click the Edit link in the Blog Posts element to open the blog post configuration tool. Then, check the box next to Reactions, edit your reactions as a comma-separated list, and click Save.
Reactions works with Layouts templates, though if your template is heavily customized, you may have to reset your widget templates for Reactions to appear. If you have a Classic template you will need to switch to Layouts to use Reactions.
Of course, Reactions isn't the only way to gather great feedback from readers; we also recently launched the Embedded Comment Form. With both Reactions and better commenting, we aim to make it easier for you to get the response and adoration you deserve.
Try Reactions now! We hope your reaction is <3.
Corrected to say that Reactions is a Layouts-only feature.
