Original poster: "The Cronje Family by way of Terry Fritz <twftesla-at-qwest-dot-net>" <cronkies-at-netactive.co.za> hello all i'm wondering: does anyone out there use RFC's? what exactly are they for, and what are the good/bad points of using them? also, in south africa, wire is sold in millimeter thickness. does anyone have a conversion table for wire sizes to thicknesses in mm? thanks a lot! pieter
