For now, the sign that you are needed will look like the bat signal the people of Gotham used to summon Batman, but with a cute cat face. They call it the "cat signal."
Tiffiniy Cheng, co-founder of Fight for the Future who is spearheading the project, said WordPress, Reddit and the Cheeseburger network have already signed up to be part of the league and that Wikipedia -- the largest website to take part in the anti-SOPA protest -- is also considering membership.
"With the current sites signed up we have a combined reach of tens of millions, if not hundreds of millions of people," Cheng said. "We are taking the network and tactics of the SOPA fight that we created and turning it into a permanent force."
As for why the signal for Internet action is a cat, Cheng said it has to do with Ethan Zuckerman's cute cat theory of digital activism, which posits that the same tools that help people share cute cat photos can also be used for online activism.
Go team internet!
