HI, I'm Eric with TURFtech and the one mainly responsible for the site since 1996.  In early 2007 I retired the site.  For awhile there was an effort to keep it going as Turftech.net.  That wasn't to successful and at present, Steve Spuhler has started a new community site for Equipment Managers at www.golftechs.net.   The original site has been resurrected as an archive site and is located at www.turftech.org.  Almost all the info is accessible.
