Here are some links I came across today grazing the web for Ecotect tutorials. I wrote an email to the Ecotect guys once and asked for software training possibilities. They did not get back to me yet. So I am trying to teach myself for now (nevertheless some introductionary training would be super, just to get the concepts).
