"'Always remember when it appears on the Net it's there forever.'" As a former journalist London's Fleet Street was my domain. Now it's a sleepy little market town in the Aylesbury Vale probably no-one's ever heard of. No trains, few buses, about three sets of traffic lights and several handy gastro pubs. I love computers and have four on the go: one for some part-time business of my wife's, a second for household matters and a third for writing. The fourth is the back up for the other three.
