Google's latest initiative "Google Plus + " went into a limited public beta today and no doubt users have started liking it right away. However, one thing which might annoy you is the volume of notification e-mails or mobile alerts that are being generated by the Google Plus social network .
Log into your Google Account (or Google Plus account) and open this link: https://plus.google.com/settings/plus. This is a link to the Google Plus settings page. The settings page can also be opened from settings link from the Google Plus settings button, as shown in this screen shot below:

You can then select to disable some of them or uncheck all options to disable all notifications. And there is no need to hit any Save button as Google automatically saves all your settings.
