I like that idea — I really do. What I'm not sure about is how to handle it over time. There are new certs issued every three months automatically, so would the cert include only the most recent payment, or reset to zero after ninety days, or include the entire donation history?

I also fear this would make getting a certificate issued much more complicated.

Maybe if you pay more you get a certificate that's good for longer periods of time? Dunno. Just mulling it in my head.
