The XFree86 Project, Inc.
I was a co-founder of The XFree86 Project, Inc., the organization that produces XFree86 window system for Linux, FreeBSD and unix in general. I helped author the by-laws, served as an officer, and member of the board of directors for many years.
I was also a core team developer for a dozen or so years. Much of my work was focused on platform support for FreeBSD.
