Nick,
Looks like once more I have been misunderstood.
I don't 'want it both ways' I enjoy a lively forum, with many different contributions, arguements and challenges. What I find a little tiresome is your CONTINUAL challenging of Lu's arguements.
No-one likes arguing, but it seems as though you can NEVER agree.
For me (and this is an opinion) these forums are best when you have inputs from many people with different viewpoints, and backgrounds. When I open a thread and the order goes, Lu, Nick, Lu, Nick, Lu, Nick and so on, I personally switch off, I close the thread and go to the next one.
None of this is meant to offend either yourself or Lu, and I am sorry that my previous post has been so mis-interpreted, as to provoke your last post.
