You can donate money to me (Brian H Wilson) using either a PayPal account or a credit card.
I don't get any financial support to maintain this site, it comes straight out of my pocket.

I am not a registered non-profit. (IHPVA isn't either right now for that matter)
If you want to make a tax-deductible donation to the HPVA, the North American chapter of the IHPVA, you can do that by sending them a check.
