We use to be able to do the payout option from the post page. I'm pretty sure that's where I declined payout the three times I've done it. Now it's on the settings page, which I guess is fine, but instead of being able to set it from the post page, there's an extra step to it. Knowing my luck, if I ever used it for anything other the split payout option, and then didn't immediately change it back, I'd forget and end up with an unintended declined post.
As it is, I'm not sure how much I will be changing it, so it's okay. Just seems like a small step backward to me.
