1. Geant4 Working Groups & Coordinators
Following principles of object oriented analysis and design, the software of the Geant4 toolkit is decomposed into categories. Usually several categories are grouped together to form a working group. These working groups a responsible for the development, support and documentation of their categories. In addition there are working groups for documentation, testing and software management. Each member of the collaboration is working for one or several working groups. The working group coordinator represents the working group on the Steering Board. They are also responsible for maintainance, tagging/releasing and quality assurance of each domain/subdomain of Geant4. Coordinators can reply to specific questions in the area of their responsibility.

2. Geant4 Contact Persons
If you wish to contact a member of Geant4 for help, support, or enhancement requests of the toolkit, your first contact should be with the contact person of your experiment or institute. The COMMON representative is the contact person for people outside the collaborating experiments or institutes.
