It seems like she hasn't even shot the set yet, but I agree with you. Scheduling would help. It really does feel like she has never scheduled any of her sets. It would save her a lot of time in the long run. We were really burned by the Britney set, too. But at least she communicates and updates us.
In terms of the birthday suit set, I'm sure it'll just be implied nudes or pasties, but it also seems like it'll just be a selfie set, which is fine. If it's not over $30, I'm not expecting too much because we've been burnt on higher pricing before.
