CSER could also be on the list, precisely because it's not just some random organization talking about how they want to reduce x-risk, but in fact is tightly connected to FHI.

For bystanders, note that opinions differ on whether CSER being tightly affiliated with FHI is a pro or a con. (Personally, I'm inclined to think that any the Great Filter is either behind us or impossible to subvert, given bonobos.)
