DonorsChoose.org is where teachers go to crowdfund classroom supplies and where awesomely empathetic people go to support them.
It's an absolutely fantastic charity and has helped tens of millions of students since its founding in 2000. Current projects on the site include a teacher raising money to buy classroom laptops for students in Worcester, Massachusetts, a push to buy bean bag chairs for a class in Section, Alabama, and more than 22,000 other campaigns.
For one brief moment in late March, there was nothing on the website. Every single campaign was paid for. What seemed like a glitch turned out to be something much better.
