Here are two community preparedness listservs hosted by Oregon Public Networking in Eugene, Oregon. Try them both and see which serves your needs. They're free, of course. Dozens of other discussion lists available on sustainability topics . The Global Ideas Bank is opening an online discussion group where people can discuss Y2K problems and mutual aid and other responses to it.
People can rate each other's contributions for their interest values.
I would be interested to know if this works on your machine.
