We missed the whole business of choosing whether or not we get hats this winterbash. Since the default option was to have hats, does this mean we'll get them?
Yes, hats are opt-in unless you previously opted out. You're stuck with hats! (folks hating hats can of course click the 'I hate hats' link to get rid of them).
I would hate not to have hats... The Winter Bash 2014 site is currently live, featuring a countdown.
