Might just be me but when selling sponsorship packages to local, national or even global companies - if we were to say yes your company will have a 4ft wide board which you'll have to have made and sent to us...OR your companies name and logo will do backflips and flash in great big letters on an LED screen right around the pitch - I know what I'd prefer.
If it helps us gain more money through sponsorship, looks smart and works ok, then I'm absolutely fine with the money being used for this.
The money potentially to be made from it could pay for a better scoreboard than the money raised by us anyway.
I completely understand anyone wanting their donations back though as yet again, the board show they cannot be trusted.
