I can claim that intelligence and the advisability of any single isolated act may not necessarily be corellated. (I can hope, anyway.) I therefore have a minor suggestion to make here. Call it "Solderpooling". Anyone intent on reworking mains power, moving full-height racks, or otherwise dealing with lethal quantities of energy, at least for the first time, put out an announcement and invitation here. If there is another local list member, arrange a visit for the duration of the risky part. We tend to do this for moving big stuff anyway, but I'm proposing it also for rewiring houses, repairing monitors, gluing with sodium cyanide (!), etc. Two pairs of eyes looking at the same procedure are much more likely to catch errors than one, even if neither is a "trained professional" (or proficient amateur). Add to that the psychological desire to do things properly in front of a visitor vs. taking short-cuts by one's self and the liklihood of mistakes might really go down. There's also the pleasant prospect of a shared victory if whatever it is works and the unpleasant but comforting availability of someone to do CPR if it *really* doesn't work. - Mark
