Administrator

You can make yourself an administrator by editing cfg/source-python/wcs/privileges.json (this file is created when WCS has been loaded once) and adding your steamid there. By default, it'll look like this:

{
    "players": {
        "dummy": {
            "wcsadmin": 1,
            "wcsadmin_githubaccess": 1,
            "wcsadmin_managementaccess": 1,
            "wcsadmin_playersmanagement": 1,
            "wcsadmin_raceaccess": 1,
            "vip_raceaccess": 1
        }
    }
}

Replace dummy with your steamid to gain full access.
