I know that I do mine at all different times during the day, I have done one late at night and the next day I did it about 5:30 AM before work and I have always gotten credit.
I have done one in the morning and turned around and been able to do one in the evening, so no the 24 hour rule is gone. I only do the 2 a day when I am off work and have the time. But, it helps for the days that I don't have time to do one.
Got one on computer usage only to get so far, after 10 minutes, to have them tell me they were working on the site. Grrrr
I've not had much luck but I'll have to try getting more than one a day.
No survey for me this morning...not even the pizza one... will have to keep trying all day... I hope they load a bunch more before the weekend.
Faith
I got one for pizzas, you had to watch 3 storyboard videos and it lasted quite a bit and made me hungry...but I finished so I should be 8 for 9 this month so far!
Finally completed todays, survey. It was painful. It was a lightspeed (not) one on home construction stores (lowes, etc.) Site was dreadfully slowed and died once. I perserved and finally finished it.
