Mark Dain Does anyone know if it's possible to buy official Let's Encrypt merchandise? Like a shirt or hoodie? I'd love to get one if it'll mean I'm supporting Let's Encrypt financially. All I could find online was redbubble.com/peop... but I don't know if this actually means money goes back to ISRG. Perhaps I could donate by how much the shirt costed?

Martijn That shirt seems to use the logo simply under the Let's Encrypt logo terms, which allows anyone to sell merchandise at 0 profit. Doesn't look like buying the shirt will in any way help ISRG, it will give you a lot more street cred though
