Uh-oh I don't really want to be known as an iStockknowitall! lol
An iStockalypse in an officialy sanctionaed and planned event, which most of the bigwigs attend and they seem to book some amazing models and locations. (Big budget stuff!)
Because it got so popular to see threads about peole wanting to start local mini meetups, they creaed an officail section for it. These tend to be smaller cheaper affairs but by some accoutns even more fun than the official events!
