The should use locale as a section instead of a prefix. So instead of localeprefix you'd use locale: prefix: '&7&cRegister&7'. The same goes for help. You'll be able to get the config files via locale.prefix instead of localeprefix. You may want to also group the database settings as database: host:. EDIT: You may also want to add a /register reload command that reloads the config from config.yml so the user doesn't have to restart the server, as it can take from 5 seconds to a few minutes, depending on the plugins the server has and how resource intensive they are.
