On the Service Categories screen, where you configure the categories into which services are grouped, create a service category for “Office Time” (it can be called anything.) Then, on the Services screen where you define the services that your village offers, create one or more services for office tasks, being sure to assign them to the Office Time category.
Navigate to the Control Panel > Service Tab > Setup > Service Options.
On the Service Options screen, specify which category will be used for office time. You should also specify a dummy member account to which all office time services will be assigned.
