Not sure how many people noticed this or if is an actual glitch. But it has happened to me twice. (I am using Mozilla Firefox, if that may be the reason why...which I doubt) It regards the polls of course. If you vote something in a poll, then you respond in the thread, when you come back to the page you can once again vote in the same poll. Not sure if its a big problem or not but it is somethign I noticed. Just thought I'd give a heads up.
