While you're at it Tim, discuss actually having a merchant contract that can't be changed on a whim. People have brought up some very good points regarding this. Right now the "agreement" (or true lack of that Jeff keeps mentioning) is worded in such a way that favors you to be twisted to fit any situation. And it has been.
These criticisms and suggestions are born out of frustration and are not personal. Other sites have contracts and do not alter agreements in a matter of hours. It's the right thing to do and I hope you consider it because it's time. If you refuse your merchants some security, you're going to lose some and it won't look good for you.
