That's it really. You may remember the threads on here about the people purporting to be from Microsoft who call about the error messages on your computer. I got called today (and should have just tried to speak in Flemish to them) and they tried to tell me about the error messages. I asked how they had got my unlisted number, and they put the phone down - shame, as I was about to tell them I use Linux. Be aware anyway and try Flemish as this guy didn't sound like either a Flemish or French speaker.
