I came across this question today, and wanted to note that one can currently donate to the Center for Health Security though Every.org: https://www.every.org/centerforhealthsecurity, which also supports setting up fundraisers with many of the features you mention.

I think you can do this on the SoGive platform. Have sent Sanjay a message.

Two options that occur to me:

1) Use that Facebook "personal cause" fundraiser feature, and say at the end of the description something like:

(Note: Because the CHS is part of a university, it's not a registered non-profit in the usual sense, and thus I can't set up a Facebook fundraiser where the money goes directly to them. Instead, this would give me the money, and then I'd donate it, get the money matched, and post receipts in here to confirm.

If you can handle the effort of a few clicks, you could donate directly at http://www.centerforhealthsecurity.org/giving

Donating directly also prevents Facebook taking a cut of 0.33AUD and 1.77%. If you do that, please post here or message me, so I can still feel all good about myself, which is of course what really matters.)

2) Just make a FB post with the description I would've used, and the link to donate directly, and encourage people to comment if they've donated. And perhaps I could share the post again later to bring it back to the top of people's feeds.

I'd be interested in people's thoughts on those options.
