36 pounds challenge

Hi, I've been doing MFP for a few weeks, but never posted anything.
But now I would like to propose a challenge to keep myself and hopefully everyone participating motivated. Here is the deal:

1. The challenge starts August 1st, 2011 and ends April 1st, 2012 = 8 month challenge.

2. The challenge is to lose weight, but slowly and healthy = 4.5 pounds/month
Over the course of 8 month this means 36 pounds.

3. On the first of each month, we report the pounds lost since last weigh in.
If you lost 4.5 pounds or more you are good to continue.
If you lost less than 4.5 pounds or gained weight, you are doomed to do 3 extra exercise routines every week till the next weigh in (in addition to whatever you are doing already). What kind of exercise? Read on.

4. On the 2nd of each month, I will communicate the three biggest losers (=people who lost the most weight in the last month). Each of them will name one of the extra exercise routines that people need to complete.
The exercise routine should be communicated on the 3rd day of the month.
Each exercise routine needs to be doable without any equipment (e.g. walk extra 30 minutes, 30 extra crunches, etc.) and should not take more than 30 min per exercise. Keep in mind these exercises will be in addition to whatever people have set as their individual exercise routine.

5. Max. 15 participants to make this easier to manage. First come first serve. Add me as a friend with message if you want to join. Communication via MFP email to keep closed group. Will send out the first message so everyone knows who are the participants by August 1st.

6. Have less than 36 pounds to lose? Participate until you reach your target weight and then maintain to avoid extra exercises.

Looking forward to it!
