Jetpack Comments replace your default comment form with a new comment system with integrated social media login options.
When someone reads an article on your site and wants to comment, they can now use one of their existing social networking accounts to post a comment.
Since it will replace the default WordPress comment form, Jetpack Comments are opt-in. To activate it, just visit Jetpack → Settings → Discussion on your Dashboard and switch on Let readers use WordPress.com, Twitter, or Facebook accounts to comment.
When activated, Jetpack Comments takes the place of your theme’s comment form. It will look something like this:
Leaving Comments
To leave a comment, just click in the box and start typing. Once you click in the box, the comment form will expand and there will be options to log in with WordPress.com, Twitter, and Facebook. Optionally, you can also enter your name and email.
Comment Options
Before you click Post Comment, you have a few checkboxes that you can check:
Checking Save my name, email, and website in this browser for the next time I comment will store your information for the next time you participate in a discussion on this site.
Checking Notify me of new comments via email will email you to confirm that you want to subscribe to comments. Once confirmed, you’ll get notifications via email each time a new comment is posted.
Checking Notify me of new posts via email will email you to confirm that you would like to subscribe to the site’s blog posts. Once confirmed, you’ll get notifications via email each time a new blog post is posted.
Once you’ve clicked any checkboxes that you’d like, you can click Post Comment and your comment will either be posted automatically or held for moderation. This is based on the settings found under Settings → Discussion → Before a comment appears.
Comment Form Settings
By going to Jetpack → Settings → Comments, you can update the following settings:
Comment form introduction: This setting allows you to change the message that appears above your comment form from the default “Leave a Reply” to whatever you desire.
Color scheme: This setting allows you to change the comment form color scheme. You can choose from Light, Dark, or Transparent.
Other Settings
Enable pop-up business cards over commenters’ Gravatars: This setting enables Jetpack’s Gravatar Hovercards feature.
Enable Markdown use for comments: This setting allows users to write their comments using Markdown.
Enable comment likes: This setting enables Jetpack’s Comment Likes feature, which allows users to like other user’s comments.
Pingbacks and Trackbacks
Pingbacks are very similar to trackbacks. Pingbacks can be thought of as a form of remote comment. When you publish a post that contains a link to a post on another person’s pingback-enabled blog, the author of the other post receives a notification that you’ve linked to their post on their blog. The pingback is then displayed on the other post as a link to your post.
Pingbacks are problematic because they are often used as a means to place spam comments on your site. You can follow these steps to completely disable pingbacks on your site:
Select Settings → Discussion in your site’s WP Admin
Disable Allow link notifications from other blogs (pingbacks and trackbacks) on new posts
Select Save Changes to disable pingbacks and trackbacks on new posts
You can also enable or disable Pingbacks for individual posts via the “Discussion” settings available in the sidebar when creating or editing a post.
