@stux I made a donation to another instance today and left it programmed as a monthly donation... which is convenient for me... check out https://www.paypal.com/donate?token=yQzv6sqdgeqfezuGYI8xodYgglFDztn1NTF6SPR-ywxASRHZrvVG4nzxu0mlBMZDdnMANhvzcsrmb_tF

I made the same donation through paypal to your instance... but it appears to me for a single time and I don't know how to automatically program it on a monthly basis. Check if you can automate it to be periodic.
