I created a community for London 2012. Not only for speedrunners, but for players that own legitemate copy on Steam (I do own it now, by regaining access to my old account and family sharing it to my main). You can talk about stuff there too, as well as share pictures, videos and even talk about other Olympic Games. In order to be able to write on other channels you need to verify yourself in the #verify channel
