My apologies. I am in the process of learning to use a new lap-top and, as I am away from home for a few days, I had enabled the lap top to receive my emails. What I have not sorted is stopping them going to my desk top as well. I will do that on Monday from home. In the meantime I have cleared the backlog so it should be OK to send the details again.
