If you live in the USA, here are a few easy things you can do: 

• Educate yourself about how SOPA and PIPA work.
• Print and mail letters to your state’s senators and representatives, urging them not to support this. Physical mail is harder to ignore than email. It piles up. You can find representatives’ addresses here and senators’ addresses here. Remember that PIPA is a Senate bill and SOPA is a House of Representatives bill.
• Call your senators and representatives on the phone and urge them not to support the bills. See above links for phone numbers or click here to get a quick list of representatives based on where you live.

Let your elected representatives know, as inconveniently as possible, that censoring the Internet is something you do not and cannot support. Congressmen care about getting reelected. If everyone reading this plays their part, these bills will be killed.
