No sure what you want to see my the way of evidence? Its been done at other clubs, it's not rocket science or reinventing the wheel.
Evidence....I explained all in my original post. I explained why and what I would like to see if you don't understand why here's a hypothetical situation to assist. Hypothetically if someone suggested raising £20 a month each from pretty much half of the current home attendance I might just want to see some evidence that was achievable. Or say there's an organisation with an annual turnover of approx £10k run by volunteers. They have a static membership the majority of which are life time members who contribute nothing finacially to the organisation. To the best of our knowledge that organisation has fund raised and delivered the grand total of zero infrastructure projects in the last five years if not longer....maybe ever?
If that organisation then tells me they want to help fund and be involved with the building of a large stadium related project I might want some evidence they are capable of achieving that before I hand over my hard earned cash and back their involvement That might take the form of funding and building a new supporters bar. That might take the form of a safe standing terrace. That might take the form of a new fan zone like the New Hotel End. I might also want evidence that they have the required number of members and the required capability to raise funds for the projects.
As I said previously you and others seem very good at talking, debating and complaining about how things currently are without actually doing anything yourself. You could put the wheels in motion on setting up a foundation tomorrow.
So if it's not rocket science and not reinventing the wheel and it truly is that easy why haven't you pr they done it?
If it's that easy get on with it and PROVE IT!
