I have been noticing and deleting a lot of double posts since the new board has gone live. I believe that 99% of it is due to people clicking the 'Back' button on their browser after they submit a post. Unlike the old site, the new site does not allow you to do this without double posting. That is why you cannot use the 'Back' button after you post. You either need to use the 'Back' scroll down menu on your browser, or you need to click the specific forum tab directly above the thread text on the current page to get you back to the thread listing page. Your cooperation is appreciated.
