Postponed: British APL Association Spring mini-conference - Friday, March 27th, 2020Due to the Coronavirus outbreak, the British APL Association is postponing the Spring mini-Conference that was to take place on 27th March 2020. A number of alternatives have been considered and for the moment the most likely action will be to merge this event with the forthcoming AGM on May 29 2020. However, this later event is itself subject to review and developing events will influence what we eventually do. Please check the BAA website for more information.
