I had the food one too about doing future surveys. However, on the very last page it told me it had a link there for my convenience to see what they meant by the food diary I was supposed to keep. Anyway, Firefox couldn't seem to open it, so it closed my whole window! When I restored the session, it said, survey no longer available. I had taken the whole survey and just hadn't clicked the button on the last page that would have taken me back to SR. And of course, I couldn't qualify for any other surveys! I wonder if I will still get these other surveys it talked about?
Oh well, doesn't bother me to miss one survey - can't expect to get one every day all month, and I have tons of other things to stress about!!
