I suggested something like that yesterday. But I could see that there would be security problems.
So I also suggested that a few folk formally request to meet some of the powers-that-be. I would suggest that this is at a venue chosen by the management - most likely at the stadium - and would be mainly to hear to what the plans are for the club and team are. Yes, we are all concerned at how things are going, but confronting management with a litany of complaints would be the wrong approach. That could come later, if dialogue is established.
We can belly-ache as much as we like here, but this is just a fan forum and the management are under no obligation to take notice.
They are also under no obligation to respond to a request for a meeting, but I would hope that an opportunity for controlled, temperate, two-way communication would be welcomed.
How you select the folk for the meeting, I don't know, since - unless I'm wrong - there isn't an official Supporters' Club.
