Thanks for the useful link and Michael K's clicky. To Abby Sale: I was upset by being described as a whiner and told to behave myself. I often get irritated about things people write to the forum but I wouldn't dream of insulting them. Of course I could do my own search for the information I wanted but I haven't got hours to spend, nor can I afford the phone bills it would generate. Besides, what would be the point of the forum if people did their own searches?
