I just subscribed, but I think that if your video was 2 minutes shorter you would get many more people to sign up!
Please check, the email subscription is failing.
I tried to subscribe but it redirected me to a failure page.
Strange. I see people subscribing fine (a little over 500 so far). Try once more and if it doesn't work, e-mail me at nico@howtocode.io and I'll add you manually.
