Thank you for this add on.
Because G+ is no longer available I replaced that one with a link to a newsletter signup page and changed the FA to /mailchimp/.
I also edited the english/modules/navbar/nb_brand.php to:
define('MODULE_NAVBAR_BRAND_PUBLIC_TEXT', '<font color="b63399"><strong> Follow Us On Social Media</strong></font>');
Finally I moved the position of the > so it was aligned with the Follow text.
It really works well.
