I suspect it won't be possible to comment on the Yuletide site until after this year's postings go live. It's been like that all through December (which is a great shame, because several of these recs have been for Yuletide stories and no one's been able to leave feedback there - and since December is the only Small Dandoms Month on crack_van, I fear it will be ever thus). But thank you for leaving feedback here - I hope the author sees it (and I totally agree with you about the exquisiteness of the piece!)
