Setup OpenCollective Account

I'd love to support the project however PayPal is awful and won't accept the information I give it. I'd love to be able to pay through Open Collective where I already have had multiple successful donations.

Thanks for a great product!

The issue does not identify any files, tests, or entry points. First clarify the project's intended OpenCollective setup and integration scope; done should mean that users can make donations through OpenCollective instead of relying only on PayPal.
