Thanks Bruce. I guess the strength of the TF is that it is made up of an eclectic group of people - some are individuals and want to remain so, others share a common background and set of interests - one such group who are having a bit of a yack here are the marine pedants - good luck to them, and let them carry on in their exquisitely precise way, although it can be a bit frustrating when a post asks a fairly simple question that drifts off into the esoteric.
I thought my initial post was fairly clear to the non card carrying marine pedants.
