Users
The User Page is for maintaining your player's account. Here you can see everyone's Username, Name, E-mail address, and their account status.
Here you can change the user's account details, including their username, email address, and password. At the bottom of the page is where you can set the user's role. If you have set up an account with an invitation code then your role will have been set to "player" automatically. If you didn't then you are set as the role "Dungeon Master". The "User Maintainer" is there if a user account is set to that role manually.
