If you haven't yet thanked each of your Yuletide Authors, whether for your main story or a treat, please take time to do so, even if it's just a simple "thank you for writing this for me." When someone has taken their time to try and write something for one of your prompts, it's disheartening to never hear, especially if they know you've commented on other things.
You might even do
a search by recipient, just to make sure you didn't miss anything!
