There are so many great contractor-related sessions at Greenbuild this year! I doubt I'm alone in trying to choose between sessions.  

Is there interest in debriefing with SCLers the week after (say Novemeber 9th at 2pm ET?). We could share the golden nuggets from the sessions we attended, saving everyone from wading through the session... Read more
