You have the option to rename the folder where you access the administration and operator area.
Important: When you rename the folder you cannot use the build in auto updater!
To rename the operator area, two steps are necessary. First rename the folder operator to something else. The second step change the name in your include/db.php file as well.
Same procedure here, you will need to rename the admin folder to something else and update your include/db.php file.
Again, please note if you rename the folder name you cannot use the build in Auto Updater anymore.
