That really narrows the window of availability if you don;t get to one until late at night! Becareful too because I have noticed that my husband does the regular greenfield survey ecause it seemed he qualified more than I. SO I do the SM one for and then the next day when he went to take the daily greenfield survey it had my email addy and info. He almost missed it because he is the only one taking the daily surveys. So be careful you could get banned by accident!!!!
