See the list above? well these are all jobs, and attached to each job is a user i think you know the deal by now, but if not i'll say it for ya. Draw inspiration from your proffesion. if you have slashes that seperate two jobs that means you get to chose which one you want to do, or if you want you could try to do both!
ex: riyo has scientist//inventor she may pick one or the other or she could fuse the two.
