Call them. 
Each office is staffed by a live talking person. Call them til they can't take it anymore. Then, call your local senator's office and do the same. 
The progression of this Bill can be tracked officially at THOMAS (Library of Congress) , then search stop online privacy act. I'd also search for the "protect ip" bill.
