Is there a grassroots way to actually have a message reach the President?

I find myself disappointed that President Obama’s moves in the financial arena have not been bolder and more out of the box. I am concerned that he is squandering his honeymoon period good will. I am also concerned that he is too beholden to entrenched financial special interest money from the campaign.

Would he read email I sent? How else could I or a group reach him?
