*Very First Thing You Should Do On G+*
Before you change your photo, make a public post or add stuff to your about section….. Go here —> https://www.google.com/settings/plus
This is your G+ Account area. You will likely want to turn off the email function OR set up a Gmail filter. Otherwise each and every time someone comments on your posts, you are mentioned by someone or you comment on someone elses post on G+ you will get an email.
No one on G+ is emailing you — You just need to update your settings.
Take a few moments right now and go check your checkboxes to make sure you are setup in the way you prefer.
