Given the number of times you've asked this question since September I thought it might be a bit of a challenge, so I took it on, reference books and all.
However, given the attitude (answer removed) I am no longer interested.
Baldric. I felt the same as when lfc4life started posing the one by one questions with no please, and no thanks for any replies, I did suggest more interaction and manners but nothing changed. I think I said if you cant be bothered why should we, but even that did not provoke a response of any kind. Why let ourselves be abused for our helpfulness?
