Communication in discussions should remain topical and to the point. However, sometimes you need to get in touch with someone you met regarding something else. Perhaps that person has some expertise regarding another topic or you want to ask them to come to the BBQ at the weekend. Both of which are things that have nothing to do with the discussion, but are valid needs.
How can this be integrated in a platform for interpersonal communication like loomio without necessitating back-channels?
