Thanks for your interest in EFF's DMCA comment search! The Copyright Office's deadline is 5:00 pm EST on February 19th, but EFF is no longer providing editing services. We are working through our backlog of comments and can not accept any more at this point. We hope that you'll take the time to write to the Copyright Office without our help, however, and you can do so by visiting:

Also, be sure to check out this guide on submitting successful comments.
Please direct any questions about this to ren@eff.org.
Thanks again and have a great day!
