We've added an affiliate scheme to PythonAnywhere. It's pretty much the standard deal -- you have a URL that you can use to link to our site, and if someone follows that URL and signs up for a paid PythonAnywhere account, you get 10% of the money that that person pays us. You can "withdraw" the money to a PayPal address once it's cleared (that is, once PayPal has told us that it's really ours and the person who's signed up can't cancel the charge).
We're running an initial trial of it now, and we'd love to hear from anyone who'd like to give it a go! Anyone outside the European Union can join, as can anyone inside the EU who is not VAT-registered. If you'd like to try it out then drop us a line using the "Send feedback" link at the top of the page or leave a message in this forum thread.
