One thing that we really like about HC is adding pinned topics (now known as "Promoted articles") to our front page.

In some themes, the tag doesn't come inserted automatically. I worked with Zendesker Arnaud to figure this out!

Add the Handlebar to your HTML

Under Homepage, add the following

<section class="clearfix">
{{promoted_articles}}<br />
</section>

Modify the CSS

/*
* Promoted articles
*/

.promoted-articles{
background-color:#f4f4f4;
padding:20px;
-webkit-border-radius: 3px;
border-radius: 3px;
clear:both;
}

.promoted-articles h3{
margin:0 0 10px 0;
font-weight:bold;
font-size:20px;
}

.bottomspace{
min-height:500px;
}

.main-column .form footer{
margin-top:20px;
}

This will add a section just for the promoted articles below the search bar and whatever introductory images/text you may have.

If you wish to change the text for something else, like Pinned Topics, go to the JS tab and add the following

// Promoted topics
$('section.promoted-articles h3').text('Pinned Topics');

If like me you are handling several languages, you can do the following

// Promoted topics
if(currentLanguage === 'Français') {
$('section.promoted-articles h3').text('Sujets mis en avant');
}

For every additional language you simply add an IF condition and keep going!
