Ah, well I wasn't thinking about a convo with more than one partner. But hmm, I'm assuming people would only delete a private convo once the topic is closed, to make space in their inbox folder. However, if there are 3 people in a convo and one of them leaves, while the others still use that convo, and deletes it maybe he still receives any new messages until he hits a separate 'Ignore' button? Likewise, we would also have the option to simply ignore a convo without actually deleting it in case there has been content up to that point that someone may actually want to keep?

Like a Mute button? Stops all notifications without deleting the participant in question?
