Next time there is a knock on the door.
An internet user has been found guilty of what police said was Britain's first "web-rage" attack.
Paul Gibbons, 47, tracked down John Jones using details obtained online after the pair exchanged insults in an internet chatroom, a court heard.
He travelled 70 miles to Mr Jones' home in Clacton, Essex, and beat him up with a pickaxe handle in December 2005.
Think! Who have you offended.
Would this happen anywhere else?
