Privacy on Google+
A core element of Google+ is its privacy features, which have been integrated deeply into the product. Google+ gives users extensive control over these features. Click edit in your profile to change which circles can view what personal details. Your name, gender, and profile picture have to be public, everything else can be restricted. You can also opt out of appearing in the search results here.
If you would like to send a message to another user, just put their name into the destination field of your posting. If the recipient is not a user of Google+, enter their email address. To save typing the email address every time, you can add them as a contact on the circles page.
If you want the permanent link to a post, click on its timestamp to see the single post. You can copy the URL from your browser to share the permalink (alternatively, you can select “Link to this post” from the drop-down menu at the top left of the post)
You can link directly to your profile using http://profiles.google.com/
. There are also non-official shorteners that use the profile number you can find when viewing your profile. (For example go to http://gplus.to/) To understand Google Plus and Circles better, go to the settings gear to Settings -> Profile and Privacy. Look for "See how your profile looks to other users." Type in a user name from different circles and you will be able to see how your info is shared according to those circles.
There is a shortcut for this under the EDIT PROFILE button on a user’s profile page. It’s a greyed-out “View profile as....” box. Click on each section to see how each person or circle will view each area: About, Posts, Photos, Videos, +1s, Buzz
