Just wasted 45 minutes taking a survey on vividence.com. I logged in and saw I had a survey to fill out. Took the time to take it then saw in my email a message from them that I should only take the survey if I meet the listed requirements. I guess I should have read my emails first. I did not meet the listed requirements.
Ugh! That stinks!! I actually love Vividence though and have never had a problem with them...I definitely like the instant reward too when you are done with the surveys!
