Rockridge Institute has started a forum.
The forum is here: http://forum.rockridgeinstitute.org/
It is still in a testing stage and only a few people have been invited to post so far while the site is being built. You can read but cannot post yet. Once the technical issues get resolved, the forums will get open to the public and you will be notified if you are subscribed to their newsletter: http://www.rockridgeinstitute.org/forms/sub_unsub_form
