Today I found out the hard way that if you ever tick the email notification button when sharing photos in Google+, this somehow then gets recorded as your default setting. When you subsequently upload photos in Picasa and add circles to be able to view them, it then uses your default setting and emails EVERYONE in your circles that you added.
This has been highly embarrassing. I added an album in Google Plus yesterday and ticked the box to email notify family members. Today I uploaded some more photos in Picasa only to find everyone has been spammed. This is very uncool. Google need to fix this ASAP!
