The official announcement has now been made by the IGF, with the following additional information about the events:
The current schedule can be seen at https://intergofed.org/documents/2nd_wmsg/2ndWMSG_Schedule.pdf 
Since we wish to announce our team as soon as possible, to allow for early hotel and travel bookings at favourable rates, please contact Jon Diamond  by Wednesday 6th June to register an entry for a specific event or events. Entries received after this date will only be accepted by Council in exceptional circumstances.
Now that the schedule is announced those who have already expressed their interest in participating still need to indicate which events they wish to be considered for.
