Thanks for letting me know! I don't actually know if I can sign on behalf of LTFF/EA Funds but let me check!

"To be clear, I'm still donating to LTFF until matching funds last, it's too good of a deal it seems"

We do have to be a bit careful about what matching entails. I'm reasonably confident that the matching itself is ~2:1 (in the sense that OP will not counterfactually give us the money if we didn't get public donations). But the *altruistic value* of the match can be much less than 3x.

Any money we receive from OP ultimately comes from OP's longtermism donations budget, not (eg) Dustin Moskovitz's personal budget or Make-A-Wish or something. So the more optimistic you are about OP's longtermist donations per dollar (https://www.openphilanthropy.org/grants/page/2/?q&focus-area%5B0%5D=longtermism&view-list=false), the less excited you should be about the matching.
