Someone asked this in an effective altruism Facebook group and I'm tired of seeing so many people not ask questions like this on the EA Forum when it's got a function dedicated to posting questions like that, so I'm just going to post them on the EA Forum myself. I'll post links to the answers to this question in the comments section of the Facebook post.
That's a good idea but the post was in a private group, so I figured that might complicate things if people aren't on Facebook or they have to join a while other group anyway before they join the conversation. I'll do it next time though. Thanks for the suggestion.
