I wrote an email to Doug a couple of days after the stadium was purchased with about a whole list of ways in which they could add funds / revenue on matchdays and non-matchdays now that we own the stadium. Nothing groundbreaking and I'd like to think that they have a commercial team who will have considered and dismissed most of them if not all already, but at the very least I'd have expected a courtesy response, not necessarily from him, but from the club at least pretending it was him, to say thanks for your efforts and all options are under consideration.
I'm not going to post them all here to be ripped apart by the negative bunch who will proclaim half of them stupid or obvious ideas, but the way I see it, better to be suggested twice than not at all.
My favourites were about turning the arena part into pop up escape rooms, which can be really cheap to put together and gain lots of easy revenue and opening up the fan village with screens on away games or street food days in the carparks etc. Anything really that makes it useful for more days than current and all goes back into the club. I doubt the email ever actually made it to him.
