this is so cool. hats off to the creators. I bet it's a ton of logistics to manage. I surfed around the site but couldn't find any information re: volunteering with them? I wonder if they need them and what kind of commitment it would be? I'd be interested!
Hack Club is run by adults (you can see the team page here: https://hackclub.com/team), and every aspect of Hack Club is also built by teenagers contributing to everything from HCB (our fiscal sponsership platform) to High Seas (https://highseas.hackclub.com), a program we're running right now.
Happy to help if you still need help setting something up for your son :)
