It would be remiss of me not to thank people. If I concentrate on one name, I hope you'd forgive me - Ian Grey, of Shades of Grey. Many other BPers and non-BPers gave valuable advice along the way too, esp. Not Saussure but it was Ian who must be mentioned in dispatches for the stalwart way he was at hand to bounce ideas off and to consider which direction to go. I'll buy these gentlemen and some others too a drink at the Awards Ceremony.
