How to add a title to a user?

You can see this photo. How can I add name administrator or moderator, like Sam here has - co-founder, but below the username not right like by him.

Hello

That’s theme specific. Discourse Central Theme uses a custom CSS to achieve this.

.topic-body {
  .topic-meta-data {
    .names {
      flex-wrap: wrap;
      align-items: baseline;

      .user-title {
        flex-basis: 100%;
      }
    }
  }
}

Custom Title. Goto user profile admin (If your admin use the wrench beside the cog)

The other Highlight iirc is just showing real name with alias.

This is how the custom title shows on one of my sites.
