Add A Friend Feature

Can you guys please add an add a friend feature soon? A lot of the people who use khan academy, including me, are homeschooled, so it would be great to be able to make friends and talk and study with them, without having to give someone your personal email, phone number, or social media.

It would be great for added competitiveness, which can often lead to higher scores.

Many people would really enjoy this

I hope to see this added soon!
