I am curious to know why so many posts that I read are from people who joined the forum in August 2011 (as indeed did I). Where there an exceptional number of new members in August? Perhaps the site was optimised for search engines and a whole lot of us discovered it for the first time? Or is it that people are most active in the first month after they join? If so, there must be a steep fall off of acitivity after the first month.
