Been there, done that -- or tried, anyway.
I get the Download newsletter, and there was a link to the poll in that. Or maybe it was to the article, with a link from there to the poll.
I selected avast (what else?) and hit the "Submit" button. At that point there was a delay and then I got transferred to my (blank) home page. No "Thank you", no look at the results to date, and I don;t even know if my vote got counted.
