I've just followed that by examining the 'Organiser' section of the YEC's web-site.
It offers merely booking form for the event organisers, for future events. The Visitors' Information for both public and trade shows (the ice-cream) is quite sparse.
I think the entry categories and competitions can only be handled by the event organiser; but I would expect delivery and collection information, including security, to be a joint effort by organiser and venue.
Eight weeks away….
It all is worryingly close to the time for exhibitors, including the traders and club stands, to plan anything. Without knowing what is really going on, or not, in the background we can't do anything more than wait and hope; though I would suggest it's not the YEC we need scrutinise, but whoever is trying to run these two parallel exhibitions.
The YEC does seem to be on the ball for advertising events, but it can't publish confirmations and details it has not received from organisers.
Have the shows even been advertised yet, in the two hobbies' magazines?
