Once the web app is up and running, navigate to the /account/setup URL to create the admin user account. Once the admin account has been created, the /account/setup path can't be used anymore. Additional user accounts can be created by the admin users at the /admin URL.
About User Accounts
In Rophako, all user accounts on the site are considered to be "owners" of the site, or, users with permission to manage and edit blog posts, photo albums, and other site features.
The only real distinction between an admin user and a normal user is that an admin user has power over normal users, i.e. the ability to change their passwords, delete them, impersonate (log in as) them, etc.
