To change settings on your account, such as notifications and privacy options, go to Settings page.
For your settings page, you can update your password, email and phone number.
There is also a Privacy section in which you can control who contacts you as well as who can view your profile. Be aware this does not control who can send you Friend Requests.
You will also find your Notification settings to adjust how many notices you will receive and where you wish to receive them. Please be aware we do not provide an option to block all Friend Requests at this time.
