Who is up for a weight loss challenge?

I'd like to do a weight loss challenge with a few members with maybe a $30-$50 fee. Then we can agree on a possible one person win, or second, and third place also. This really motivates me to do better. The rules would be a pic of your scale holding up the word of the day to ensure it is the real pic of you on the scale. It would be a percentage of weight loss. I'd like to get it started around 9/15, we can use the cash app or quick pay. If we all feel comfortable we can do a challenge every 30 days to keep each other motivated.
