Mr Wheatley,
        I know that it is almost "that" black day in the lives of all Brits, bu
cheer up. There are a lot of newbees out here who have a lot to learn. 
Learning enough about complex computer systems to do one's work is a real
challenge, usually a pleasant and rewarding one. Please, make the learning
experience positive.
