It seems to me by the wording you have mentioned that they are wishing you good luck in your continuing efforts on starting a career with MSP. With no class scheduled for now or in the near future, I don't see how it could be anything else. Call Framingham HQ or Mass HRD (I'm not sure who runs the MSP test) and get a definitive answer from someone who knows what they are talking about. You run the risk of getting fed rumors if you don't do something like this. Good Luck.
