While at work the other day, SWMBO and her colleagues were chatting about people they mutually knew. Following on from that, one of her co-workers was able to call up our old address just with SWMBO's full name (admittedly it was 2yrs out of date) but she was acting 'smart' and not telling how she did this. Allegedly it wasn't using the electoral register.
My curiosity is well and truly piqued; any ideas what website she might have been using?

Oh, and we've always been ex-directory in the 'phone book.
