Correct.
The screenshot I shared is actually from the bottom of a recent email to donors.
The email itself was actually a really gracious thank you note.
I just went back and reread and that is all it is. It does not contain phrases like “additional needs”, “additional funding” or contain any ask language.
It just says thank you.
I value iNaturalist for many reasons but their extremely thoughtful treatment of donors is definitely high on the list.
