|Nothing here about Community Notifications|
I like the new Community feature of Google+. It is great having another cool way to keep up with developers worldwide, but I hate all the notifications. I neither need nor want an email every time a member leaves a post. Unlike other parts of the Google+ world, there is no setting for turning on or off Community notifications in the Accounts -> Google+ section. But don't despair, the switch is hiding in plain sight.
On Community page itself, below the community's logo and membership total, next to the Action drop down, there is a button with a bell icon. Clicking the button turns notification on and off.
