The Koala Rescue services are a voluntary group that rescue check up upon...and transport injured koalas...and then return them to their natural habitat after they have been cleared by vet services in Australia. If you phone them to help an animal, or help them in any way, you are recorded as being a MOP....member of the public...."yes the MOP said that he looked distressed" ... that sort of thing.
Does anyone else have funny code names for things that no-one else knows?
