You're quite right bigdave it hasn't been asked before. I always check before asking though as people who like helping can get a bit tired of answering the same question
It has been asked before - several times - but the point I was making was that to insult someone by telling them to check using the search box without first making sure that it works is unnecessary.
If factor30 gets fed up giving out the same answers many times then all he has to do is ignore the question.
