There's an amount of common sense to this. Simply put we're fine with you sharing information with others as long as you get permission from us first. We'd prefer it if you did this more because you didn't have time in-session, or because someone wasn't at the session for you to tell them, rather than as an alternative to telling people yourself, n your own words.
