Perhaps a thought should be given to tasking a more suitable organisation to run such a scheme as SoA in future.
A group with the time to spare since they don't (yet) deploy and can easily give up weekends for a worthy cause. They're representative of the target audience, and even speak the same language.
I believe that they could do a better job of producing a website, and they've years of experience at organising traffic at airshows.
Ladies and Gentlemen, time to call in the ATC Team.
