Each one of these roles signify what type of viewer you are; whether you are simply reading and commenting on another's work, or you're creating your own stories for others to enjoy. Each of these are shown in order from the simple Viewers, to the mighty Guardians.
Viewer: A person who can read or comment on others' work.
Creator: A person who can write stories for others to see. These don't necessarily have to be personal or made up, although we hope they are all in the works of fiction (i.e. refrain from real world events). Remember to source your content regardless if it is yours or someone else's. Although, please do try to use your own work.
Inventor: A person who can create massive projects, with or without groups. Inventors can allow Creators or other Inventors to help work on their projects.
Guardians: The admin(s) of the website that hold(s) everything together as well as fixing any kind of problem. It is possible to have the permission to become one of the Guardians, however, certain guidelines must be followed and as long as there were no previous offenses with the individual.
