Remember Curio from Zengobi, that unique brainstorming and project management app we found a couple weeks ago? As a thanks to all the publicity they've been getting lately the company has decided to offer Curio Basic for free - but only until midnight, EDT on Tuesday, August 7th. All you need to do is enter some basic information at the promotion page, and a license (a $39 value) will be emailed to you. Definitely note, however, that one of Zengobi's terms is that they can cancel this offer at any time (probably in case they get slammed with too many requests), so I would recommend you run, don't walk, to snag your copy. After all: you can't beat 'free'.
