After reading a meta post on Software Engineering about opting-out of Winterbash 2016, I figured I'd ask the community here. This will be our first chance to participate in Winterbash, but it is an opt-out program. The mods would just need to let the CM team know by December 13th.
Yes, it is true that this year's Winterbash will run from 19 December to 8 January.
We at Retrocomputing could opt out as a site.
There is also another way. Any individual who wishes to opt out will be able to do so. There will be an "I hate hats" button on the site. You will then not be awarded hats and will not see the hats of others.
My personal view is that Winterbash is a bit of fun, let's do it. There is always a hat for visiting a new site, so it could attract more people here.
For those who don't know, Winterbash is series of challenges set to the users of StackExchange at the end of the year. Each challenge successfully completed earns the user a hat. Some of the challenges are easy, some difficult and a few are secret! -- And, no, the moderators don't know what the hats are before the start.
