How to use Google Wave with Discussion Groups
You can use your Google Groups alias as a participant in a wave. This will make the wave accessible by all members in the group. Also, when you add new members to the group, they will be able to access all previous waves.
You can create a new Google Group by going to http://groups.google.com.
Your group settings will determine who can view the waves sent to the group. If you select Anyone can view the content, the group waves can be viewed by anyone.
