You can get one of these fine Tor T-shirts for contributing to the Tor project. There are three primary ways of contributing:

• A tax-deductible donation to the Tor Project.
• Operate a fast Tor server that's been running for the past two months: you are eligible if you allow exits to port 80 and you average 100 KB/s traffic, or if you're not an exit but you average 500 KB/s traffic.
• Help out in other ways. Maintain a translation for the website. Write a good support program and get a lot of people to use it. Do research on Tor and anonymity, solve some of our bugs, or establish yourself as a Tor advocate.

If you qualify, mail tor-tshirt at freehaven dot net with a brief explanation. Be sure to specify a size (S/M/L/XL/XXL), a backup size if your first choice isn't available, and a shipping address.

Please take a look at the striking conversation-starting bright green color below: we only have a limited number of shirts, so make sure you'll actually put yours to good use. You can also see the shirts in action — add your own photos there too.
