Hello all, I have an apology for the list at large. I turned on a 'feature' of Microsoft Exchange to forward any mail I received whilst I was 'out of the office', and as well as forwarding my mail Exchange very kindly sent the occasional automated reply without any provocation. This should not have happened, and I turned off the 'feature' as soon as I spotted that this was happening. I am very aware of the potential problems automated mail 'helpers' can cause when one is subscribed to a mailing list, and I take care to ensure that anything I do does not create havoc for these lists, however this feature of MS Exchange did not appear to work in the described manner, so I am sorry for any inadvertent 'list noise' I caused, and I hope I stopped it soon enough. Andy (the other one)
