Ian many thanks for the info re the data base, most valuable. At the same time the same person Prof Norman Coombs runs a very super course Called 'Adapt it' via the internet/easi net. I can highly recommend the workshop (3 weeks! $150.00) next one is in April and cheap at twice the price. E.A. will join me in the above sentiments. Alan.
