This may seem a bit in the weeds, but I have typically paid extra at Greenbuild for the access to the materials after the conference - we use that to develop presentations back to the teams who are not able to attend. For many years it was helpful - getting some materials to help folks see what they missed.  Last year they went to a new service... Read more

We haven't... Read more
