No, I didn't actually sign up to participate - these days I can't really handle the stress at this time of year. But the great thing about Yuletide is that you can write 'treats' even if you're not signed up - so you can look through all the fandoms requested, see what people have asked for and see if something catches your eye - then you can just write them an extra story on top of their 'real' one and add it to the collection! I've never done it before, but I'm so glad I did! And then you get to read all the other stories anyway. :)

Before Yuletide starts there's a period where people can nominate fandoms, and they may not get through - they have to be small and rare enough. And even if they get through, if they're not both offered and requested then obviously they won't make the grade either. But yes - it's a great way to read stuff you'd never even have thought of otherwise!
