I NEED YOUR HELP!

Hi guys, I need your help. I'm currently writing a dissertation and I hope you can take a little time to do my online survey. My study is about print magazines and their websites. Well, basically about whether free online content offered by magazine branded websites is influencing the demand for print magazines. Are they substitute, complement or two independent goods? Anyway, my questionnaire is not that complicated as I explained. It may take you less than 1 minute. Since there are research ethics of our university, please do the survey only if you're over 18 years old.

Thank you very much in advance!
And if you could, please pass this to as many people as you can. But do ensure your friends are over 18 years old. I would be so appreciated!
