BarCamp Melbourne takes place in just 10 days. Creative Contingencies has thrown some coins in the hat to sponsor the event and help ensure it's free for attendees. Would-be BarCampers do have to pay $10 up front to secure their place, as spots are limited. Too often, people sign up, but don't show up. A small financial commitment seems to work to reduce the number of no-shows. If attendees do turn up, they get a refund, or the option to donate their fee to a carbon offset scheme.
