Pretty neat set up, Jim(Meggawatt) Neal (nlemerise) Bob (guzzle) put it together, well, had it revised. It is contacts accross the US for when traveling, you would have a safety net of sorts.
It does not look like the RHN forum is working, but it included a members map, with contact info. The problem with it is always the same, it was a forum, and it cost. So eventually what it turns out to be is either a master contact list, or 1 person with members numbers to call out to in a time of need.
