Sorry not to put these slides up earlier – my journey home took seven hours, arriving just before midnight. Fine as far as York, but packed train thereafter (no chance of working on this train)delayed by two hours due to flooding near Newcastle, then with Metro cancelled and no taxis in Newcastle I ended up getting the only bus running home, which took a further two hours to my street due to entirely gridlocked traffic. ! I’ve strung all the main slides into a single (big!) file, not in the order in which we used them, as I dipped and dived into various presentations during the day. Great working with you all.
