Nice to have this Xmas event, Kleeder. I hope I have enough time this year to take part in at least some of the battles.
The formats I can do are all the NSFs (classic, normal and +), 0cc, Mario Pants normal or extended and, maybe, maybe MIDI (though I'm a little rusty and idk if I can write anything decent in an hour).
I may participate in an OHB involving the visual formats, but that's far from being my specialty.
As of now, I don't know yet what days/time would be better for me. Just do as your heart feels, Kleed, you're a good hoster.
