A registry of .org sites

from their site:

When you buy a .ORG, you're buying much more than a mere domain name. You're linking your organization - your cause - to a worldwide community of mission-driven organizations that are trying to make the world a better place. Click here to learn more about our World Voices campaign that promotes these organizations in the global .ORG Community.

Through the registry for .ORG, your organization is linked to a well-established brand of trust and integrity. One of the original top-level domains (TLDs), .ORG became the domain of choice for organizations dedicated to serving the public interest, and today .ORG is considered one of the most trusted domains on the internet.

Nonprofits, foundations, philanthropic and cultural institutions, religious, civic, arts, social and fraternal organizations, health and legal services, clubs and community volunteer groups ... if yours is a noncommercial entity, people expect to find you in the .ORG community.

Commercial businesses also benefit. Registering a .ORG lends credibility to the activities of a charitable arm, protects your brand name registered with other TLDs and gives customers another path to your website.

Representing the interests of this community, .ORG, The Public Interest Registry maintains a leadership role in advocating internet advancements, addressing privacy and security issues and improving internet access around the world.
