I am nuetral / undecided about HR811. If you have decided one way or another, the Electronic Frontier Foundation has an advocacy page for supporting HR811. You should be able to edit the message to indicate whatever view you have; support/rejection/something more nuanced.
From the the EFF HR811 advocacy page:
Along with requiring machines to produce a voter-verified paper ballot, H.R. 811 mandates random audits and many other critical reforms. For over three years, EFF has been helping Rep. Rush Holt move this legislation forward, and support from individuals like you has been crucial in garnering an astounding 215 cosponsors. Hundreds of activists joined EFF for Washington, D.C. lobby days in 2005 and 2006, and thousands of letters have poured in to Congress.
Now those efforts are paying off, and victory in the House is within reach — take action now and fight for fair, transparent elections.
