I will write thank you emails as best I can, but the MSF donation page and tools are .. a bit lacking. 802 donations. Can't download.
Donation pages of life-saving NGOs are .. so crummy. Maybe tech people who want to do good can help fix that? Big need, area of expertise.
what was wrong with the MSF one? Seemed to work pretty easily
If you reach out to MSF they may be able to provide the names, but privacy policies prob prohibit providing the emails.
No, they actually provide it all to me. (Unless donor picked anonymous). I just have to click one by one. No download. :-(
