If you’re in the DC area, there’s an emergency meeting of the DC Tech Meetup to get involved in advocating against SOPA and PIPA legislation.
If you can’t make it in person, you can use the EFF’s online form to write your representatives about SOPA and PIPA.
Don’t wait until it’s too late. The Internet is a vital part of our freedom. Well-intentioned legislators could damage that greatly while trying to solve problems they don’t understand fully.
