CCMWG was organized in 1959. Missouri Writers’ Guild is celebrating 100 years in 2015, I believe. If I remember correctly, MWG started in Columbia.
January 1997 was the first Well Versed Poetry quarterly and September 20, 1997 was the first Writing Workshop (the forerunner of the conference). It was held at the library and 55 people attended. In February 1998, Amy Christianson named the newsletter “The Write Stuff.”
I noted those important dates so long ago that I don’t remember where I got that information.
