There are different types of voluntary units, organisations and clubs with a specific knowledge and skills, which are sometimes even better than these belonging  to the proffesionals. It is a very serious chalenge to find a mechanism to use these specific knowledge and skills in more efective way. The specific competence of such kind of volunteers could be very useful, but for the moment there is no a valid system for cooperation with them and usualy it happens to negotiate on the spot how they exactly will help which means loosing a time.
