PlanBig is a great website where you can launch your plan to a bigger crowd than just your own network and invite others to get involved. Or if you prefer, get behind an existing plan and help make it happen. Think of it as a way of networking with people who want to do more than just socialise.
Because PlanBig is designed to fit in with the way you want to connect online, it's easy to send PlanBig updates to your favourite social networks like Facebook and Twitter.
Start by taking a look at some of the plans already posted and you'll understand: PlanBig.
