Great job inviting so many people.
Initially I was not happy when I got invited - not that it wasn't needed but...I still wasn't happy about it.
Now I am SOOO glad I am doing this.
Hey, just think of how many people you will have helped make healthier.
Even if they initially want to kick your @ sign, think how much healthier you may have helped them become. (if they are up to the challenge)
Good Luck
