I think one of the ways fans could help change the situation would be to turn up in huge numbers every week.
McCabe isn't going to throw any more money at it so the only way things will change in any significant way is if he finds a buyer. The only thing we can do as a group to make the club a more attractive proposition to prospective buyers is to turn up week in, week out at BDTBL and make the club as saleable as possible.
I'm sure selling a club with an average gate of 25,000 (with the subsequent increases in turnover) is easier than selling a club averaging 18,000.
