How do I request coderwall be added to the list of Social Accounts?

I would like to link to our company Coderwall team so the link shows at the bottom of our site.

I've read the following article but can't find an option to add additional accounts or perhaps links and icons manually. http://help.squarespace.com/customer/portal/articles/522434

This was a useful source for the Icon Fonts - http://drinchev.github.io/monosocialiconsfont/
