Obviously you have a valid plan which however I do not agree with.
I do not think that boycotting will achieve your objectives and will upset an equal number of fans to those that you please.
The bank I would have thought is only interested in the club paying off the overdraft not how many people attend or who is in the board room.
Whoever is there will probably have the same aspirations - make some money and that can only achieved by having a successful team.
If we have a successful team and a large number of people attending games we are also more likely to be taken over.
