Wolfgang, thanks for taking the trouble to post those sites, on first reading I was unable to access the first site but have just gone back to it and it made interesting reading, I have bookmarked it and will read it in full when I have more time.
guest jaze, I didn't take offence, Kendall can be very funny sometimes, if you want a real laugh the first 3 times I read his post I didn't get that it was a joke.
