2 things I discovered about Google Plus today -
1) When you send a email to a Google Plus contact - it's like a Facebook Message and a copy gets delivered to your email. I wondered if you the contact is in your Gmail address book if it would go as a regular email.
2) You can view your own profile as someone else. Click on your name on the top left and below the "Edit Profile" button you will see a text box " View Profile as " and you can add any name and see how the view is. ( tip: choose "anyone on the web" and double check to see what photos you are sharing.
