Welcome to PC @Alexander98

I'm one of the few who doesn't use social media. Instead I email or private message on forums or by phone texting. Or I use DreamHost, which is an award willing subscription-paid platform for emailing and is a brilliant way of communicating online.

Your friend could join an online pen-pal site. This is a really excellent way of networking because it's comfortably one-to-one, and won't involve trouble makers and those who delight in using the 'Like' or 'Dislike' button which social media thrives on.

I hope that's useful.
