OK, it looks like we have enough interest to have a contest.
Here's my suggestion for the rules.
Firstly, decide whether you want to play the PRO version ,which may cost you money, or the LITE version which only costs you pride and the last pitiful remnants of what used to be your self esteem.
All weights must be taken in a constant environment - ie on the same scales, at the same time of day and in approximately the same clothing state.
Your starting weight and target weight must be declared between now and midnight on 31st May 2014. Please don't overstate your starting weight - thats cheating and not in the spirit.
Closing weight is 3 months away - on 31st August 2014
The winner is the PRO player who both makes their target weight AND loses the highest percentage of their original weight. If they don't make their target weight, then they can't win. The winners prize is to nominate their favourite charity.
Every losing PRO player who made their target weight donates £25 to a charity nominated by the winner. Every losing PRO player who fails to make their target weight donates £50 to the nominated charity. We can do this with a just-giving page, so there will be full transparency if anyone welshes.
Its up to you if you want to post updates.
We work on an honour system, but anyone doesn't believe the winner's claimed weight, they may challenge it, and an independent member of the forum living nearby can go and verify it. A failed challenge costs another £25 in the pot, but a successful challenge eliminates the winner, and they have to then pay double what they would have paid (either £50 or £100) to the charity named by the new winner.
Any dispute is ruled on by whichever of the mods are not participating.
How does that sound?
