Yes, and yes

You need to refer more than just 1 person before you get the badge

They must register.

I've made over $3500 since I started with this platform in April. I live in Denver so there's always work available.

It doesn't really matter; I'm not certified and have never had any issues.

I have 8 likes but still no badge so I'm not sure what we need to do to get it :/
