Hi there.
Firstly, please do not double or triple post and use the edit button if you have anything to add.
Secondly, I think you'll need to at least be an adult to work as a GM. If you want to work as a GM you will need to
contact Outspark themselves for job opportunities. GM isn't some voluntary online job though. It's a real life job where I'd assume you'll need a resume and cover letter and everything if you're serious about getting one.
