Please add option to disable Traffic Quota
It would be great to have an option in the Server Config under the Web tab to disable the Traffic Quota and related fields, so that all sites can just be "unlimited" - and avoid confusing clients with an unnecessary field containing a negative number (as most non-tech-savy individuals would not know this means unlimited). This could probably be placed above the Traffic Quota notification settings. When disabled/unlimited, the notification fields could be hidden/disabled.
