Hi Leila There are all kinds of folk on this net, some techies and some, like me with a foot in both camps! Enjoy the ride, take what you want and dump the rest but it is a wonderful way to keep in touch with the issues even nerdie ones. <smile> The real power of this particular net is in the archive which is worth exploring, all kinds of good material there! Enjoy Alan. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
