The Social tab contains the settings for Disqus, Social Links and Social Shares.
Here you can add and edit your Disqus integration for blog comment hosting services.
You have the ability to add social links like Facebook, Twitter, Pinterest, YouTube and more. You can designate the icons to match your design and where the social buttons should link to.
This is where you would provide your ShareThis Profile id to be able to enable the ShareThis functionality on your website.
Similar to links, Social Shares allows you to designate the icons to match your design.
