Consider donating to support Wikipedia

I urge you to consider donating to the Wikimedia Foundation, the organization that funds, runs, and supports Wikipedia and its sister services. Only with universal, free access to information do true democracy, liberty, and equality have a chance in this world. This is your chance to help make it happen.
