For those who are interested, Yuletide nominations have begun.
Note that this is an optional part of the process, even if you want to do Yuletide; it’s only necessary if there’s something specific you know you want to request. (Or offer, since some people nominate based on what they’d be interested in writing.) If you do have something in that vein, though, nomination is the only way to be sure it will be available this year.
(If you’re not sure what Yuletide is in the first place, or want more info, there’s finally an up-to-date FAQ you can consult.)
