Have you ever met someone, taken their details, then, er, lost them completely?
Or heard about some great business, remembered half the name and forgotten where it's located. If you have, 192 - not to be confused with a once hip Notting Hill restaurant - is the site for you (www.192.com).
It searches directory enquiries, the electoral register and so on until it finds a match for whatever scanty details you provide. Indeed, if your quarry has a very unusual first name, you can search on this alone: for example, only three people are named Rhymer in the UK.
One drawback for the rich and famous is that they too are on the electoral register. Want to know where Jude Law or Richard Branson live? No problem.
192 is a potential goldmine for stalkers, direct activists and the like, though it records all searchers' details. In the new economy, it's getting more and more difficult to hide.
