I'll be running it this year and having people put their presents in chests at the Christmas tree behind the Aequitas shops north of spawn just like last couple years. There's a ice skating rink for boats there as well if you haven't been there already, check it out.
So basically just like any other year, post your name here if you're interested in participating in the event. I'll be taking names starting now, and then on December 21st I'll stop taking names and then I'll randomly select partners for the event and tell you who it is in game or in PM.
For presents there's really no rules for how expensive it has to be, but it should be something thoughtful at the very least. Just don't throw a stack of something in a chest.
Hopefully we'll get more than three people in!
