I have sent your post to a colleague of mine from South Africa who worked on a project with me in Riyadh, Saudi Arabia. His name is Alwin van Lynden. I do not have his direct e-mail address with me since he left us, on completion of the project, a few weeks ago. However, I have sent an e-mail to another colleague who works with him for the same company who was also attached to our project. Will post his detauls if and when he responds to my message.
I am very pleased, too, at the magnanimous responses that this wonderful man Hugh Karunanayake makes in this MB. Thanks Hugh!
