As we continue to receive countless requests to donate to SPR, we have now temporarily added such an option.
Important: Do not donate to “support” SPR or to encourage additional updates, as the research project is mostly completed. Donate only if you want to thank for work already done. And no matter how much you donate, you will get zero influence on what we do or do not publish.
Donations are possible via PayPal (any currency) or credit card (USD, EUR, CHF).
