I'm confused...how do we take the before pic and display our "before weight", so that its "official"?
edit: And since there is money involved and people may become unethical, I cannot see a way to come up with an offical "before weight". Sure, you can have a before and after picture, but you cannot figure out the amount lost between the two. Perhaps we should postpone the contest until we find a solution.
edit2: Maybe have the before and after pics and have a panel "vote" or go by the honesty system. There is no way I can imagine we can gather accurate weight data from everyone. With the "scale" idea, its very easy for lets say to someone to add an weight to the back of the scale to boost the total (and i'm sure there are ways to manipulate the end weight). Damn people, why is there such dishonesty in the world!
