Just a quickie.
TMC has announced the dates for this year's Burn Jita: April 25 through 28. That's this weekend.
There's also every single reason in the world to assume that things will kick off at least several hours early. After all, they did both last year and the year before. And I wouldn't put it past the Goons to start things off earlier than that this time. Last year, a number of people tried to sneak a few expensive things into Jita before the "deadline." This did not go well for them.
Don't join the dozens of people who lost freighters and jump freighters last year and the year before! Good luck!
EDIT (21/Apr/2014): Talvorian Dex makes an excellent point in the comments below: a good solid third of the losses last year took place in the systems surrounding Jita. So watch yourself anywhere in the neighborhood!
