Hello Thje Duib Dei,
Thanks for your question about adding social icons into BoldGrid. Currently, the first way to put in a social media platform that is recognized by BoldGrid is to install a brand new Inspiration. When you add your contact information you will see the option to add the social media option there. If you're using a social media platform not recognized in the list, then you would need to add it as a custom menu link. The icon cannot be currently added as a graphic using the existing functionality. Here's a list of the 33 recognized social media platforms (Note: email is part of list):
facebook.com
twitter.com
vk.com
bitbucket.org
codepen.io
dribbble.com
dropbox.com
flickr.com
foursquare.com
github.com
gratipay.com
instagram.com
jsfiddle.net
linkedin.com
[email protected]
pinterest.com
plus.google.com
renren.com
reddit.com
snapchat.com
trello.com
tumblr.com
twitch.tv
weibo.com
wordpress.com
xing.com
yelp.com
youtube.com
slideshare.net
stackoverflow.com
stackexchange.com
soundcloud.com
steamcommunity.com
vimeo.com
vine.co
If you're already working in an installed installation and you didn't add the social media option during the Inspiration installation, then you can go Menus (in the Customizer). Click on Social Media menu and then add a custom link. If the URL is recognized, then the social media icon will appear in the menu. I hope that helps to answer your question! If you require further assistance please let us know!
Regards,
Arnel C.
