Davek, I admire your dedication and passion, and I suspect you are completely correct in your assessment of the board (not the brand). However, I question whether a confrontational tactic will work if it is employed from the off.
It's less about the club, and more about the image of any supporters group by other supporters, that vast silent majority. If you come out guns blazing, many will write you off without listening to your points. However, if you come out diplomatic and cordial, you may find a massive undercurrent of disquiet among the fanbase. Then, depending on the action (or more likely inaction) of the board, you have a vast collection of supporters on your side and willing to take the board on.
Currently, I believe there are 4 groups of Evertonians:
Anti-Board
Untrusting of the Board, and unhappy with the board, but not necessarily militantly so
Pro-Board
Don't care
The don't care people will never care while the results are solid, so let's ignore them.
The trick is to unify the first and second groups to try and bring about change. If done correctly, and change fails to develop, you'll find less and less of the third group, and probably even less of the fourth group. At which point a confrontational tact is far more likely to succeed.
