There has been some discussion about having a central resource for CGT material over the past few years. Just a few days ago at Games at Dal 2015, Aaron Siegel took the initiative to actually get it going at combinatorialgames.org.
Aaron has already posted lots of basic info over there, including some notes on getting started in CGT, some reference materials, and information about upcoming conferences.
Please check it out and continue to check back as more information gets added. Thanks to Aaron for getting this project started!
