Google Plus messaging is based on your 'Stream', which is both a public broadcast tool AND your private inbox/sentbox. By toggling your privacy settings and target reader(s), you control whether your Stream post is a shout or a whisper.
In Google Plus, you send a private message by making a Stream post, but adding the extra step of specifying the target person's name. There is no separate screen or separate container for private messaging... your confidential conversations are displayed on your Stream screen, but only you and the target person see the message.
How to Send a Private Message in Google Plus
- Type a new Stream message in your Stream screen.
- **Type or click the target person's name into the sharer list.
- **Delete any circles or individuals whom you don't want included.
- Choose 'Disable Share' from the drop down menu at the right of the message.
Result: the target person receives your message on their Stream screen, but no one else can see your message. Additionally, the target person cannot forward ('reshare') your message.
Yes, this Google Plus private messaging is strange and counter-intuitive. But try it for a couple of days. Once you get used to the extra step of specifying the target person's share name in your postings, you're going to like the power of having private group conversations.
