…may indeed break your bones, but making unsubstantiated allegations on a web forum will probably cost you tens of thousands of pounds.

An article in The Guardian draws attention to the dangers of treating the web like a playground. If you publish something on a forum, it's going to stay there, so you'd better be prepared to back it up with hard evidence. Alternatively, you could post to a well-moderated site such as PCAdvisor.co.uk or, better still, like my old mum always says: "If you can't say anything nice, don't say anything at all."

Incidentally, all PC Advisor readers are brilliant people of excellent character.
