Big Dropbox fan are you? Got plans for the weekend? Cancel 'em. Dropquest 2012 begins right now. If you're unfamiliar -- it's the storage company's internet scavenger hunt that involves a series of puzzles, challenges and, erm, origami. If you complete the game, you'll get 1GB of extra space for free, but if you come in first place, you'll get 100GB free for your entire life, while 10 second-placers get 20GB for life and so on. You're not allowed to ask for help on the company's support forum (you'll get disqualified) and you're competing against at least half a million other fans of the service, but if that hasn't daunted you then head on down to the source link and get puzzling!
