Okay, I'm not sure you guys know exactly how G.io is working for non-subscribers, or I'm totally confused.
Examples ...
1. If I find a different G.io group, let's say by search, click on the group (Digitrax-Users or IBM, for example), I can't do anything except to request access (or join) the group. I don't see any "public" areas. So, I'm not sure what you mean by the difference between "email" or "password" accesses.
2. Yes, Subscribers and Members appear to be synonymous ... If "members require approval before being allowed to join", then there are no "Public" areas to view. I'll try setting Spam Control to un-restrict membership and moderate new users.
3. And, Message Policies: to "allow non-subscribers to post" which appears to require a moderator, and see if that works for us. Of course, this creates more work for moderators, but that might give us the access level we need.
Thanks for the assistance and patience.
