Hi Yuletide person!
I am working on my yuletide letter and hopefully will have it up by Monday. However, everything you might need is in the signup I promise, the letter will just restate the same stuff with more prolixity and add extra optional prompts. Crossovers, experimental formats, interactive fiction, and all the other opt-in stuff is explicitly ok!
Also, my laptop decided to go from "worryingly creaky" to "extremely scary bluescreen" about an hour ago, so if the letter doesn't appear on time that may be why. Sorry! I will still have internet access just not as easily if the laptop goes. In the meantime, you are as always welcome to scan down previous entries in this tag if you want to know more about what I like in Yuletide.
