If you have electronic mail, you can join the Green Building Discussion Group. Most members are American or Canadian, but others from the United Kingdom, Australia and Germany add their unique perspective to the discussion.
Members ask questions, answer questions, discuss and debate.
After getting a feel for the group and the topics, they begin to ask questions and contribute their own thoughts. Here's how it works. Members send email messages to a special address. Those messages are copied to all other members. If you join, expect to see between 20 and 50 messages a day from the list.
