Winter Bash 2014 will be starting soon, and if this meta Math post is to be believed, it is now opt-out rather than opt-in. That means that unless the moderators of a given site inform Stack Exchange that they don't want to participate by December 1st, that site will be included.
However, that raises some question as to what the status of this site will be. We don't yet have pro tempore moderators appointed. They may or may not be appointed by December 1st. A strict reading of the policies leads me to believe that we would be included automatically, but it could just as easily go the other way.
What are the plans for Winter Bash on this site? If there is no definite plan and we want to judge the community's opinions, I can modify this into a discussion question to do the necessary polling, but I figure it's better to check whether there's a clear plan either way first before making such a post myself.
For what it's worth, I'm in favor of us participating, but I'm more than a little bit biased in saying that.
