There's a DRM petition on the Entertainment Consumers Association Website (thanks GamePolitics). This is more open-ended than the typical petition where your signature voices agreement with a premise, as it asks you to supply your opinions on Digital Rights Management. This all has a specific purpose, as they are looking to collect consumer's thoughts on the topic for presentation to the US Federal Trade Commission:

The FTC is holding hearings on the issue of Digital Rights Management (DRM) and End User Licensing Agreements (EULAs). The ECA respects the careful balance that must exist between the content community and the customer, and agree, that piracy is an ever-present challenge for the trade; it is also becoming evident that consumer rights are being diminished.

We acknowledge that these are weighty and topically-important issues, without easy solutions, and we are pleased to see the FTC providing a forum for thoughtful discussion of the matter. We wanted to give you, the consumer, an opportunity to express your opinions on DRM, which will be delivered to the FTC.
