Trolling through my “draft” entries (this one is actually from Nov 2003) I came across this site: LCMS Council.
The purpose of the group is..
“…to be a resource for locating existing knowledge about Learning Content Management Systems and to encourage investigation and discussion of issues concerning the future of the development and delivery of learning content. “
I’m not sure if this organization has really held together; the material on the site is pretty dated, but the white papers are interesting.
