Mike,
People should listen to your opinion on a trade. You've shown that your a good commish, you've shown that your dedicated to a solid world/team, you've shown that your willing to be vocal about your thoughts. If you think a trade should be vetoed, I'll assume it deserves a closer look than perhaps I gave it the first time around. It doesn't mean I'll change my vote, it just means I'll look at it closer, perhaps form a more informed decision based upon what others are saying. When I see a trade come thru, I know I won't always get a chance to cast my vote one way or the other by the time the day is thru, I see no harm in allowing me to change my vote, if upon reflection I think it needs to be changed. I can do so, and have done so with my end of the year awards, if a Trade is so much more important (and I agree that it is) then I'd like to have the same ability. In however many seasons that I've played, I've only had 2 or 3 instances where upon further reflection I wish I could have changed my vote. Once from a no to a yes, and another 1 or 2 from a yes to a no. Giving me the option, gives me and everyone else more power. Perhaps a noob that doesn't quite understand the game votes yes off the bat, then when its raised in the coaches corner, he now sees why he should have voted no. I don't see a drawback to it, other than perhaps server space and programming time, which may or may not be a big deal.
