That point was puzzling me too. The only difference between being a concerned shareholder making suggestions to the BoD, and being a member of that BoD making the same suggestions would appear to be fees and options.
With all the pledges made on here, plus any that might be available from the previous letter-writing campaigns, and those sent privately, it wouldn't surprise me to see an alernative slate being presented, and with 30-40-50 million shares possibly pledged it could be quite a close-run race.
One good point about a proxy fight would be the full disclosure required from both sides.
