I don't know if anyone is interested, but the question and answer platform Stack Exchange is trying to start a Worldbuilding subsite at http://area51.stackexchange.com/proposals/63276/worldbuilding?referrer=swdmssOCTC7T8d_GnskAZQ2
. Right now we are trying to get enough support to put the site into beta. I am super excited about it and think it could be a great place to get good answers and friendly advice in worldbuilding for games and stories. If anyone is interested, please check it out.
