Drat, drat and double drat

I missed signing up for Yuletide :(

I know it's a little thing, but after the year I've had it's really disappointing.

With my computer being down, I had to wait till I got to work to sign-up and it being Monday and busy; I didn't get to my computer till 2 hours after sign-up.

Oh well. I made it a step closer this year and actually nominated my fandoms. So I'll start thinking about next year and edge ever closer!

Does anyone know if you can write treats if you're not signed up?
