I've been mentoring new users since the start of Steem - was a mod on steemit.chat and helped hundreds if not thousands come onboard Steem. I've even created an account and community called @userhelp / community here and Introduce yourself community while waiting for onboarding to start to happen.

I'm a mod in dozen's of discords. I know what it takes to keep people here. I'll write more as it's late where I am on some ideas to help retention and to onboard. Thanks!
