I know another forum where there is private members area, and to access it you need to be a fully paid up subscriber. Maybe that could be the way to go.
But as someone mentioned in a earlier post, a small subscription each year would help towards the running costs, trophys for any cabin only matches or memorial events.
Even if it was as little as a fiver a year. It would be a token of appreciation to the people who devote time and effort to keeping the site up and running.
