Donating to CPDL - is the address correct?

[choralia]

I sent a donation to the address mentioned in the "donate" web page linked to the CPDL home page. A check was sent on my behalf by an U.S. resident. This is the result:

our donation to CPDL was returned by the U.S. Post Office. I sent it to 696 Boynton Avenue, San Jose, Ca 95117 and it was returned unable to deliver to this address. Did I copy it wrong? or have they moved?

Any clue? Donating to CPDL looks quite difficult... why don't using more normal means nowadays, such as PayPal, credit card, etc.?
