Regions allow the Agency to dispense appointments to interpreters in particular geographic regions.
In Agency => Settings => General Settings you'll find a switch labeled "Use Regions" switch this on to activate this feature.
Appointments are tied to regions by location. Once regions have been activated you'll see a field in locations marked region. This will allow you to tie the location to a region.
Interpreters can be associated to one or more regions. They will only see appointments that are linked to one of their regions. This means an interpreter who is willing to travel farther could be tied to more regions then another interpreter who doesn't want to travel so far for work.
You'll also see a new area where you can message all interpreters associated to a particular region.
