This is the fun part!
There are dozens of New Fringe members, with all sorts of skills. No artist is an island, so let's get collaborating!
Whatever project you're working on, have a think about what skills you don't have that other Fringe members might be able to help you with. Then put out an advert (via Marketplace) for someone with those skills! (You can also use social media or just chat to someone)
If they agree to work with you on their project, then afterwards tot up the hours of work they've done, and send them that number of Fringecoins (via Banking). Remember, one Fringecoin is for one hour of work, and everyone's hour is equal.
