This seems like the most appropriate place to put this since most of the gift giving for Christmas will be happening at the ball or around that time. What are your thoughts on a "IC Gift Giving" post/meme? There are a lot of characters who will probably be giving out gifts to more than just the people they got for the exchange, but I doubt everyone has time to log out every single gift they give/get.
Maybe it would be easier to have a post where people could list who their characters give gifts to and what. That way it won't be some IC plothole where people are like: "Well my character gave your character blah-blah!" and others are like: "We never knew our characters go anything."
