I read the title and guessed the problem you'd be talking about and came in here to voice the exact solution you described. So yeah, it works for me.

Well, the question is whether or not your contributions to the chat are removed for everyone, or just for you.I mean, my guild girlfriend could still show my irl girlfriend the messages I sent her if they're still in her inbox.If I hit "leave convo," my comments would still show up in everyone else's inbox, right? I imagine so, since that is how it normally works.Not that it really matters, because I'd just like to organize my inbox a bit. But its something to think about.
