wg-c@dnso.org reaches everybody in the working group. If you crosspost to wg-c-1, wg-c-2 or wg-c-3 you are reaching again a subset of the same people. As sometimes I sleep, go to the bathroom, work, etc... it might take more than three minutes to add somebody to one of the lists. You will be added within 24 hours of your request. Don't expect anything during weekends. Javier
