Generally, everyone can hear what goes on in the journals, so you can filter it to keep it private to yourself, or between certain people. You can ask Shirley or Walter to show you how to do it. Just to warn you, however, no matter how well you filter it, everything in the journals can be overheard by the Malnosso.

But since you're new here, I doubt you know any of these people better than I do, so describing them would be pointless.
