What's going on here?

  • Problem: People don't email broken@lvl1.org every time something breaks.
  • Why?: My guess, no quick access to email/computer to email the group.
  • Solution: Deploy a number of Amazon Dash Buttons around equipment. If something breaks or we're out of stock of something, instruct patrons to press the corresponding button.
