From Citizendium, the Citizens' Compendium
Please donate to Citizendium
We are in continuing need of funds to pay for hosting our servers. We have set up a PayPal account to receive and accumulate your donations. You do not, however, actually need a PayPal account of your own—credit cards are accepted. When you get to the Donate page, look down towards the bottom of that page to find the link to make a credit-card payment without using PayPal.
Donations Also Welcome By Check
Donations to Citizendium may also be made by writing a check payable to Citizendium Treasurer and mailed to:
4729 East Sunrise Drive
Tucson, AZ 85718
N.B. At this time, your contributions will not be income tax deductible because we are not yet registered as a non-profit organization. Donations are handled by a private individual (Hayford Peirce) in a PayPal account separate from his own personal accounts. If you are having any trouble with the above donation button, please let Hayford know at firstname.lastname@example.org. Thanks!
