I've "favorited" several communites (the Ensemble community, for example). I assumed that since Ensemble shows up in my subscriptions I would receive emails when there was activity in that group. My settings are the defaults: hourly, on updates, on comments. Perhaps, I'm going about this the wrong way, but I would like to be able to subscribe to a community (and not just a conversation) and get email updates on activity. How do I set this up?
