Aldo, Let's face it, there is nothing you or I or anyone else on this list can do to bring some order to the Internet. It was built to be chaotic and exceeded its specifications ;-) There is nothing you can do about that. On your list, however, you can define the policy that you want, and ask people who don't like it to take their discussions elsewhere. And you have the means to enforce it. People are free to set up another list somewhere else if they're not happy. But you'd sooner convince the NRA that guns are bad than convince the "problem" users you're complaining about that they don't have the right to do what they're doing. Eric
