@mtnwkr And I like that as an option. I bet others would lighten up to doing that as well.
Main ID is whatever you want to converse with and what's exposed to google. The custom title can be used to share your name to the group. I'll look into my ability to set specific permissions towards the view of the users "Custom Title" so that limited to those who are registered and logged in, and not recorded as google search content.
