The only donation options I see are credit card and PayPal.
How do I donate by mailing a check from my IRA’s trustee, as a Qualified Charitable Deduction?
Thanks for your will to donate! and sorry for the delay to answer.
I don’t know what is a IRA’s trustee, but if you are based in US, you can donate by check via SPI as we are an associated project here, see:

Otherwise, we can’t accept check because they are very expensive to process, so we kindly ask you to chose another mean, see here for other options:
