I keep getting this message today from Greenfield while in the middle of surveys:

"The system is temporarily unavailable. Please check back shortly. We are performing system maintenance to improve your future experiences at SurveyCenter. Thank you for your patience."

It seems like I'm the only one who gets those type of messages while in the middle of taking surveys. It is so frustrating b/c I'm usually in the process of completing a long survey, and a lot of times I don't have time to check back later.
