It was epic. While member sites broadcasted their support, we blasted our “cat signal” into the sky in cities around the world (on Batman's opening night!)

Though the launch of a grassroots campaign to protect the Internet is worth celebrating, there's nothing like an IRL event to feel the power of the Internet community. We had such a great time at the Internet Defense League launch parties that we thought we'd share a few highlights.

You'll get an IDL member card to carry around in your wallet, handy proof that you are, in fact, a superhero charged with defending the internet.

Cat Flashlight

You'll get your own personal cat signal torch light. Short range, but good for striking fear into the hearts of the free internet's detractors.

Donate $150

You'll get everything above, and either a) an Internet Defense League nameplate for the door of your house or office or b) a hand-drawn illustration of you as your choice of superhero. We weren't sure which we liked better, so you pick!
