EFF is great and I would encourage anyone to donate/join. If you get a chance to attend, they frequently speak at the DefCon conference in Las Vegas, NV (http://www.defcon.org) and field digital rights questions.

They also produce useful info for anyone concerned with digital privacy like the "Surveillance Self-Defense Project". If nothing else, it's gives some perspective on the complicated legal state of data security and communications.
