It looks like you can take 2013 off from MU.
I had heard from a friend that somewhere in the fine print it says that by accepting the MU $ you are locked into participation with the process "forever", and should we fail in meeting the requirements, they can ask for/take their money back.
I haven't found such a statement. I know that instead of incentive payments, there will be penalties, but to actually take the incentive money back? Anyone else hear of this?
